I do not think there is a real market for young or normal hides. However you might be able to "create" one among the local reenactment comunity, or similar--"sustainably hand raised, humanely havested rabbit pelts". Me, I just want them for myself. I am raising American Chins, and so they are sort of too gorgeous to part with for me--yes, it is a pain, so is knitting. If have the patience for one you have the patience for the other I think. I think you have to like either the process or the product.
If I did not like either I would stretch and smoke the hides as rawhide animal toys and try that market before attempting the clothing market.
