I designed a quilt using applique blocks and matching quilting motifs, and played around trying different background colours, sometimes using all applique, sometimes all quilting only, and of course, mixing up quilting and applique.
Above are all quilting motifs, below are all applique blocks.
All quilted but with black instead of white thread.
All applique on a different background fabric.
It is amazing that quilters ever get any quilts made when there are so many variations and options with just one quilt design.
