ugly is in the eye of the beholder- there are fabrics one of us may hate that the next person may oohhh and ahhh over- the ugly swap is proof of this- and some really spectacular quilts have been made from ---someone elses ugly fabric-
so if you really don't like them- take some pictures and offer a trade- someone will think they are lovely and will happily trade with you something they feel is ugly which you love.
