Knitting Basics: Slip Knot Cast On + Printable Guide
I think we’ve all been there. You’ve knit a beautiful pair of socks, a hat or sweater only to find out that the cast on ended up too tight. Even though you had swatched and everything seemed to match the needed gauge (if you have missed my post about gauge, please check it here: https://lifehack.craftorator.com/121-guide-to-crochet-knitting-gauge.html)
Some projects need a cast on with more stretch to it than your usual cast on might offer. So today I’m going to show you how to make one of the awesome stretchy cast-ons (and there will be a series of them for you to learn). It’s super easy and the result is pretty, sturdy and definitely stretchy.
This cast on, also known as Buttonhole or Jeny’s Stretchy Slip Knot, is simply a string of slip knots lined up on your needle. It creates a very elastic edge that is great for the tops of socks, the ribbing on sleeve cuffs and mittens, and other places where you want a lot of stretch. When followed by ribbing, the cast-on edge looks great — it makes neat little accordion folds that follow the stitches. On stockinette, however, the edge looks unfinished, and I would reserve its use for edges that will be seamed. Additionally, it is great for adding on stitches at the end of rows. Slip Knot cast on is perfect for adding stitches at end of row, buttonholes and any very stretchy ribbed edges.
Warning: This cast-on is a bit finicky about the kind of yarn you use. You should use yarn that is a smooth texture and uniform in width.
