You probably need to take into consideration the market area -
I think it is fair to ask for - at the very least - the cost of replacement materials - even though you did donate the item -
Example: You would have to spend $15.00 for materials to make another one - charge at least that - then more as you think customers might be willing to pay.
A lot of people have absolutely no idea how much fabric and sewing stuff costs.
If you wanted to - you could put up a sign that says: "Of course you could make it, but when? and for how much?" and then put up a materials list. :twisted:
Good luck with the bazaar.
