I knit it in 3 pieces; top, sole & strap. It went very quickly (about 5 hours total) & took just over 1 skein of the Classic Elite Flash! in Lotus Blossom. The fit is much better, since it isn't ment to fit a range of sizes & I like that more of my foot is covered.
Wish I knew a cobbler! I would love to knit a pair that could be attached to a hard sole.. that would be so much fun!! :)
