Crochet three long pieces then braid them together and stitch closed to make an eternity scarf. I'm thinking that this could be done with knitting too, since I can't/don't crochet.

I LOVE this stitch!
Arm knitted a blanket. Used simply Maggie's tutorial on knitting a scarf. 12 Skeens of yarn, 15 stitches. Amazing!
