I have seen some very big award winning quilts and my first thought was WOW, who pays for their thread! Some of them have no space unquilted. I just quilted a king top this week and it took two large spools with simple line quilting. My last hand quilted top I did quilt very close patterns with several colors of thread. But, are we getting carried away with all the quilting that ends up making the quilt top stiff? Just thinking.
