Making Baby Leg Warmers (craft)

I thought I would try to make baby legs or baby leg warmers. I'm not sure what I think about them though. I have seen them before and wanted to try it. I WAS going to make and sell at a craft sale, but im not yet sure. Is this a one time thing or a keeper? My little chunk is showing them off for yah. Bad phone picture tho... Sorry. What do u think?
