I did it I got a pair of flip flop socks done for DS#1. I used my good old stand by pattern for a cuff down round heel sock, then made it up as I went along. Took days, as he wears a size 11 1/2 shoe.
My yarn back stock has gone down so much I had to buy yarn to keep making anything!! The photo is of some of the items I've put together, I wish I had thought to get a photo of everything.
I have a few patterns to put out soon, just need to find more hours in the day. However if you see something you like E-mail me and I'll try and get you the pattern or the link to the pattern if it's not mine.
