I don’t know why, but I’ve never actually used the crocheted cast on method on a project other than for provisional cast ons where it will be removed. It makes such a pretty clean edge, and it’s easy to work, but it never occurs to me to use it.
It’s not super stretchy, but it’s also not too rigid. It has a nice balance, and it’s very attractive looking. It perfectly mirrors the bind off method I use the most. The only drawback is that the last stitch looks slightly different from the rest because you have to slip it off your crochet hook onto the needles instead of working it like the rest.
It took me a while to figure out the best way of using this cast on method at the end of a row. I ended up inserting my hook into the last stitch of the row below and pulling out a loop to use in place of a slip knot. This does distort that stitch, but I can’t decide if that is enough to make this not a good choice for a cast on that’s not going to get covered up. It just looks so nice compared to some of the other options!
