well, I have sold many quilts, mostly through consignment shops, for prices I am happy with. Now I am through with consignment (whole nother story) and just trying to reduce my inventory to gain more space. So yes, the prices are insane in my Etsy shop right now. Would I do a special order for a similar quilt at those prices? HECK NO.
So the low prices you see might be other people clearing out "slow movers". I have seen some very pricey quilts on Etsy, like $2700 for one 20" x 30".
