These fabrics are different combinations of print, script, and dots on white, grey, and cream base fabrics. As the name suggests, these would make great background fabrics for appliqué blocks. I think these would also make great additions to quilt top adding interest to an otherwise plain block. There are beautiful decorative scripts, some with scientific drawings, and others with overlapping patches of different writing styles. There is a great selection to choose from, but be quick, they are very popular!
