Do you want to be able to say "I made her a quilt and I have done all I can to keep the family together", or do you want to be able to say "I made her a quilt I thought she would love"? Obviously she doesn't love/like flowers on fabric. Why would you use it? To spite her? It would be better to replace it with a solid than use a fabric you know she has already said she doesn't like. Where is the love in that? If the cost of the fabric is really the issue then sell the floral fabric and save up for the replacement fabric. People love quilts because of how the finished product looks, not because of the hours that was put into them - otherwise we would all cherish the child made products in the stores. What could be made more dearly than the labor of a child? It's a hard world.
