Doing It Wrong: How to Work a Provisional Crochet Cast-On Knit Hem.
This post is about knitting hems the way I do, which is probably wrong somehow–though I think this is pretty close to the standard method for working a knit hem from a provisional crochet cast-on. It’s useful for patterns like Grays Harbor and some other things in the 2017 mouse army queue, and also makes a really nice cast-on for short socks worked from the top down, in my opinion. (It’s pretty stretchy and neat-looking, as well.)
With this hem, you first work a provisional crochet cast-on. There’s more set-up detail at the link, but basically it works like this:
using smooth waste yarn similar in weight to what you’ll be working with for the project (mercerized cotton is great for this), work a crochet chain. It’ll need to be longer than your number of cast-on stitches–if you add at least 10-15 chain sts to the number of stitches called for, it’s easier to manage. Pick up your stitches (sidenote: start from the end of the chain, not the beginning; it makes it easier to unzip the crochet stitches when you’re ready) and then work your called-for number of rows or rounds–say 17 total. The picked-up stitches are usually called the foundation row, or the foundation loops.
Once you’re knit 16 rounds (16+foundation=17), transfer the foundation loops to a spare circular needle. A needle that’s a size or two down from your working needle makes this a little easier. (As a sidenote: the very last loop always feels like a half-stitch to me, but in this example you’re working in the round, so it will be knit together with its corresponding stitch just like the others.)
After transferring your stitches, unzip the provisional cast-on chain.
Then knit each live stitch together with its foundation-row loop. Continue in this fashion until all the stitches have been worked.
With that done, you’re all set with neatly knit hem!
