As promised, here's a tutorial on the crochet provisional cast-on method. This is a really useful technique, applicable to any number of project types: making a bottom-up sweater, but you don't know what type of edging you want? Use a provisional cast-on and you can easily pick up your stitches and work the bottom edge when you've finished the rest of the knitting. Want to knit toe-up socks? Use this method and work a short-row toe. Interested in knitting a shawl? Many, like the Flower Basket, ask you to start with this cast-on to create a tidy top edge. I could go on, if I didn't have a nasty cold making my brain not work good. Anyway, I hope you find this useful!
Steps 1 & 2: Make a crochet chain using waste yarn -- preferably, something smooth and in color which is readily visible against your working yarn, in approximatley the same weight. To make your chain, just grab the strand of yarn with your hook...
Step 3: When you're done making the chain as long as you need it to be (plus a few extra) cut the yarn, bring it through the last loop, tug gently to close (gently! You're going to have to undo that later) and tie a knot in that end, to remind yourself that this is the end you'll be "unzipping" from later on. Now flip your chain over and take a gander at the bumps -- they kinda look like purl bumps, right? -- on the back side (assuming the front side is the "v's" you see as you are working the chain.) You are going to pick up stitches through these bumps.
Step 8: Remember how I mentioned in Step 3 that you should make a little knot so you will know from which end to unzip your cast on? Don't you feel smart for doing that? Pat yourself on the back, and maybe go pour yourself a glass of wine to prepare yourself for the next steps, which involve stitches being all naked and loosey-goosey.
Step 9: Take the end with the knot in it and bring it back out through the loop you drew it through to close your chain -- thus re-opening your chain. Now give that end a tug (a gentle tug, just in case there was some snaggage when you picked up your stitches.)
