Ticker Tape is a style of quilt-making that uses small scraps. Where patchwork involves sewing precisely cut fabrics together (right sides together) to make a larger fabric, ticker-tape involves sewing scraps down on top of a background fabric. With ticker tape, scraps are usually placed like a puzzle. This puzzle is not usually planned in advance, but rather evolves as you cut and attach scraps. You can see lots of examples of diverse ticker tape quilts here.
