The Cable cast on is very similar to the knitted cast on. It starts the same way as the knitted cast on, where you make a slip knot and place it on your needle and then knit through the loop to form the next stitch. After this step, instead of knitting another stitch and putting it back on the right needle, you insert your needle between the two stitches to form the next loop and then place that back on the right hand needle. You continue making stitches by going between two stitches to make the loop.
Where I use the Cable cast on:
- When I need a firm edge such as the border on a blanket
- When I need to add stitches at the end of a row
- Making a one -row buttonhole
Backwards Loop (e-Wrap) Cast On is a very basic cast on and is one of the cast ons often taught to beginning knitters. It starts with a short tail and a slip knot placed on a knitting needle. You then take the working yarn and wrap it over your thumb , insert the needle under the loop on the outside of your thumb and let it slide off your thumb onto the needle and tighten up the stitch.
Where to use the Backwards Loop Cast on:
This is an elastic cast on that can be used for most projects needing a stretchy edge (hats, gloves). You can also use it to add stitches in the middle of rows (i.e. the underarm of a top down sweater or at the base of the fingers of a glove.) You can also use it to add stitches at the end of a row. The loops between stitches can look sloppy so you need to pay attention to how you make your loops.

Here’s a picture of the swatch. I cast on 44 stitches so that I could have a 40 stitch area surrounded by a 2 stitch garter stitch edging. I started using US 2 (3.00 mm) needles and then switched to a smaller US 1 (2.50 mm) needle for the last part of the swatch. I did a section of garter stitch, then stockinette stitch, then the color pattern using the lighter aqua blue as the main color and then switched to using the darker teal blue as the main color. I finished the swatch by doing a section of sockinette stitch on the smaller needles, followed by a section of garter stitch.
