I don't live in FL (not sure why it has to be state specific, but

) and I've never tried to sell anything at a craft show. However, I've been to a many of them and don't recall seeing knitted things (although that would certainly be cool). The only thing that even comes close to what you're talking about is a Christmas bizarre held by my community every year. I see
crocheted items there, but most of the items are small and not very time-intensive (which is fine as long as they sell, I guess).
Do you sell your knitting at craft shows? I would think that you'd have the same trouble as people who sell there stuff online--no one wants to pay you what it's worth in time and effort.
Interesting question. I hope you get some good feedback (even if the person's not in FL).
