I knew I forgot something, applique. You do need a great deal of scraps for an applique quilt. I like to have all the block backgrounds from the same fabric to help tie together very different blocks, but the applique pieces are usually from whatever scraps I have on hand.
If you have a lot of different scraps of the came color. You can pick that color and use lots of different prints for various applique pieces in blocks to tie the blocks together for a pleasing effect. Clear as mud, right? Example: one block with an apple, the apple fabric is tiny white dots on red; one block with Sun Bonnet Sue wearing a dress and hat of little silver angels printed on a red background: one block with a cardinal bird done in a red star print: and a mitten in a predominately red Christmas print. All of four them will look nice together because of the reds used in the applique, add that scrappy pieced border and you have a stunning quilt. Debra in VA See my quilts at
