Repost from last year’s Socktopus Club:
For the cast on edge of Fiori di Zucca.
You’ll need to be familiar with the long tail cast on, aka double cast on, continental cast on, sling shot, two-strand, Y cast on, german cast on. Knittinghelp has a great video tutorial for it.
A doubled tail long tail long tail cast on basically takes the tail, doubles it, and continues as normal. I learned this from JC Briar, an absolutely amazing teacher. Lucy Neatby also refers to this in her knitting videos. The doubled tail strand, which sits like scarves around the base of the stitches on the needle, gives a lovely rolled cast on edge, and also helps give a good elasticity to the cast on. Don’t pull tight on the tail strand, just pull it so that it sits cleanly under the stitches. Too tight, you’ll lose your nice elastic edge, too loose and it’ll look sloppy. Experiment to find just the right tension for you.
I start with yellow and blue spitpliced yarn to help you see which bit of yarn does what. Blue for the yarn that comes from the ball, and yellow for the tail end.
