I am still working on the EZ Green Sweater. I have one sleeve finished and about two-thirds of the other one knit. Now usually when I am getting close to completing a project like this, I will work on it steady until I’m finished. But not so this time! I have temporarily set aside the green sweater because I simply fell in love with another pattern.
It’s the Bold Blox pattern in Issue 103 of the Knitter’s Magazine. There was just something that totally intrigued me about this vest. I am not usually someone who knits straight from the pattern in the book or magazine — but here I am, knitting way on this pattern. I did make some modifications to the colors, choosing a different combination that the original — but I did decide to use the yarn called for in the pattern.
This is another unusual choice for me — I almost always subsitute the yarn called for in the pattern with something similar but more likely to be in my stash or available locally. But this time: I took the plunge and splurged on Malabrigo Worsted in six colors. (Yep – 6.)
I finished the yoke of the vest last evening and am now starting on the body of the vest. This is knitting up quickly and boy, oh boy, do I like this yarn! It is simply scrumptious. Lovely feel, wonderful stitch definition — it has it all.
The second picture shows the front of the vest. The yoke and the first sleeve is complete. The sleeves are knit in 1 X 1 rib and form a cap-style sleeve.
The third picture is of the back. I love the color combinations! I am especially in love with the raspberry pink colorway (Geranio). {I would knit something in just this color if I found the right pattern.} But I also am very pleased with how the different colored blocks in the yoke knitted up.
Details:
Pattern: Bold Blox — available on Ravelry. See link below.
Yarn: Malabrigo Worsted – Colorways: Geranio, Cypress, Pink Frost, Pearl Ten, Emerald and Red Mahogany.
Needles: US 7 (4.5 mm) and US 8 (5.0 mm)
Gauge: 18 stitches = 4 inches.
I have covered the basics of how to make a Gauge Swatch and calculate your stitch and row gauge in my previous three posts. Today’s topic will cover some basic math to help you estimate the yardage that you need using your yarn, your needles, and your gauge to make a sweater.
Let’s say you want to make a sweater using yarn from your stash and you need to know if you have enough to make it. To make this estimate, you need the measurements for the sweater you want to make. If you are using a pattern, the finished measurements should be stated within the pattern – ideally on a schematic. Some patterns may only state the desired measurements within the text of the pattern and you may have to read through to find them. If you are making the sweater without using a pattern – you would use the measurements of the individual who will be wearing the sweater.
The image below shows a schematic for the back of a sweater of a drop sleeve sweater. The back is 28 inches long from the hem to the neck and it is 20 inches wide. Both the front and the back of this type of sweater are essentially rectangles.
Schematic of Back/Front of Sweater
The schematic for the sleeves of this sweater are shown below.
Schematic of Sleeve
At this point, you have the numbers you need to calculate the number of square inches of fabric that you need to make for this sweater. For the front and back, multiply the length by the width on the schematic and then multiply that number by 2. Using the numbers from my example above:
20 * 28 = 560 560*2 = 1120 square inches for front and back.
The sleeve is a trapezoid shape. The formula for the area of a trapezoid is:
[(b1+b2) * h] / 2
Where b1 is the width at the bottom of the sleeve(8”) and b2 is the width at the top of the sleeve(15”) and h is the length of the sleeve(18”). Using the numbers from the sleeve schematic, the area for one sleeve is 207 square inches. Since you need two sleeves, you then need to multiply the area of the sleeve by two. (414 square inches)
Now, here’s a short cut – if you place your sleeves next to each other so that the tops of the sleeves are parallel – you have a parallelogram. To get the area of this parallelogram you simply multiple the width(15”+ 8” = 23”) by the length(18”). Try it – you’ll get the same number as above.
Add the square inches for the front and back to the square inches for the sleeves and you have the total number of square inches of fabric in the sweater. Now that you know the total number of square inches of fabric you need, you will need to use the yardage and weight information of the yarn you want to use to estimate how many skeins or balls of yarn your sweater requires. The yardage per weight of the yarn will be found on the yarn label – see image below:
You will use the yards per gram value in the estimate for total yardage. Now you need to knit a swatch. The swatch should be in the same stitch pattern that you plan to use for the body of your sweater. This swatch does not need to be the same size as your gauge swatch, but it should be wide enough and long enough to get an accurate weight, length and width measurement. After you knit this swatch, you will measure its weight using a scale that measures to the nearest tenth (0.1) of a gram. Next measure the length and width of the swatch and multiply these values together. This gives you the number of square inches in your swatch. Now divide the number of grams by the number of square inches.(Do not round). You now know what 1 square inch of your yarn weighs. This is the number you need to calculate how much yardage you need for your sweater.
Example: My swatch measures 3.5 inches by 4.5 inches, which gives me 15.75 square inches. The swatch weighs 9.6 g. Dividing 9.6 by 15.76 gives me 0.622 g/square inch.
Here’s the final set of calculations:
Take the total number of square inches of fabric and multiply it by the number of grams per square inch. This gives you the total weight in grams for your sweater.
Total Number of Square Inches * grams/inch2 = Total grams of fabric
Total Grams/Square Inches = (1120 + 414) * 0.622 = 954.148 g
Now take the yards per gram value from the yarn label. (For example 218 yds/100grams). Divide the yds by the grams to get the number of yards in 1 gram of yarn. (For example: 218yards/100grams = 2.18 yards per gram.) Multiply the total number of grams of fabric by the number of yards per gram to get the total yardage for the sweater. Using the numbers from the examples above:
Yards per gram = 2.18 yds/g
Total Yards of Yarn = 954.148 * 2.18 = 2080 yds
To determine the number of skeins, balls or hanks of yarn you need: Divide the number of yards by the number of yards in the skein. Or divide the total number of grams by the number of grams of the skein. Remember that you will want one extra skein for swatching. (In my example, I would need 9.5 skeins, so I would want 11 skeins with one extra for swatching)
What to do if you don’t have the yarn label
To determine how many yards of yarn you have when you do not have the yarn label or any information, simply measure out 10 yards of your yarn and weigh it. Divide the weight by 10 and you have the weight for 1 yard of yarn. Now weigh the skeins/hanks of yarn and multiply by the weight of 1 yard. This will give you the number of yards for each skein/hank.
I have decided to blog about various stitch patterns from time to time. So I am starting with the time honored basics: the garter stitch, the stockinette stitch and the reverse stockinette stitch.
This discussion assumes you know how to do a knit stitch and a purl stitch. If you are new to knitting and are not familiar with these two stitches, click on this link: http://www.knittinghelp.com/videos/knit-stitch.
Garter Stitch: this stitch pattern is made by knitting every row, turning your knitting at the end of each row. (You would get the same effect if you purled every row – but most knitters prefer to knit every row). If you want to knit garter stitch “in the round”, you would knit one row and then purl one row – so most patterns using garter stitch are for flat pieces rather than circular knit pieces. The pattern produces a knitted fabric with ridges on each side that is essentially reversible – it looks very much the same on the right side as the wrong side. It takes two rows to make 1 ridge. The garter stitch is great for borders because it will not curl and lays flat once knitted. Many afghan and baby blanket patterns have a garter stitch border and it is often used as the basis for wash clothes and placemats.
Stockinette Stitch: this stitch pattern is the most commonly used knitted fabric. This stitch pattern produces a fabric with flat “V” shaped stitches on the right side and bumpy stitches on the wrong side. It is also known as flat knitting, tricot or jersey knit. Stockinette stitch consists of knitting one row, turning your work and purling one row if you are knitting a flat piece. If you are knitting in the round, you knit every row. Stockinette stitch fabric curls on the edges and at the top and bottom – it makes a good fabric for the body of a garment, but usually requires another stitch pattern for edging and or borders. It also stretches lengthwise when worn.
Reverse Stockinette Stitch: this is exactly what it sounds like – it is simply stockinette stitch fabric used with the purl side as the right side. It has all the properties of the stockinette stitch, but in addition, it will also stretch widthwise. You can see how the 3 stitches differ in the picture below:
If you look at the pictures of my teddy bear baby blanket – you will see how the teddy bear is formed by using the stockinette and reverse stockinette stitches together to form the pattern. This is a good example of how they can be combined to form textured patterning. Aran knitting patterns often combine stockinette, reverse stockinette and garter stitches as part of the textural patterning. Again, here are examples where the stitching is actually very straightforward and easy – but produces a fabric that looks complex because of the wonderful textures.
As promised in my last post, my Trinity Stitch Slouchy Hat was knitted in January. This is a semi-slouchy hat knitted in the trinity stitch. The inspiration for this hat came from a thread in the Harry Potter Lovers group on Ravelry. The thread was about the knit hat that Hermione Granger wears in the Deathly Hollows, Part I movie. Here’s a picture from the movie:
There was a great deal of discussion about what stitch was used for the hat, but most of the comments were in favor of either the daisy (star) stitch or the trinity (bramble) stitch. So, I decided to give the trinity stitch a try — and here is the end result:
Pretty close, I think.
I knit the hat using Paton’s Classic Wool yarn on size US 8 (4.5 mm) needles. Colorway is “Bright Red”. I also wrote the pattern for this hat as I knitted it up, so that I could share it with others. Here’s a link if you’d like to download it: Trinity Stitch Slouchy Hat.
I had to convert the Trinity Stitch Pattern so that it could be used in the round. Directions for the trinity stitch knit in the round are included in the pattern. If you download this pattern and enjoy knitting your own hat, please leave me a comment. 🙂
This is another unusual choice for me — I almost always subsitute the yarn called for in the pattern with something similar but more likely to be in my stash or available locally. But this time: I took the plunge and splurged on Malabrigo Worsted in six colors. (Yep – 6.)
