I just made a queen size quillt for some one and the material alone was $110.00. It took me 14 hours to make the top, from washing fabric to finished top. Quilting will take another 8 hours and binding about 4 hours.
I don't think a box of fabric, even great fabric, pays for the hours it takes to construct a quilt. The fabric would have to be worth about $300.00. That workes out to $12.00 per hour which is cheap.
That is what I charged for this particular quilt.
