The cutting instructions on page 2 of the jigsaw puzzle pattern are for a baby quilt sewn with 6-inch square blocks, but you'll find cutting info for larger quilts with either 9-inch or 12-inch blocks on page 5.
The jigsaw puzzle quilt is most effective as a scrap quilt, but it's fine to use each fabric more than once, or to devise a color scheme. Patches required for individual blocks are small, making the jigsaw quilt a perfect stash-busting pattern.
I think this design looks good with a few black, or 'empty, puzzle pieces. Squares that end up on the outer perimeter of the quilt are sewn in black to help them drop out of the design -- use other colors if you wish.
The quilt finishes at about 30" x 42". Add or subtract blocks and/or rows to change its size. See page 2 for cutting and layout instructions.
You'll need a strip that measures at least 2-1/2" x 22" for each fabric you plan to use in the quilt. Choose light fabrics, darks, mediums, warms and cools, and be sure to add some black blocks.
Binding: about 170 running inches of doublefold binding that finishes at 1/4" (Quilt Binding Strip Instructions)
Backing: 1-1/4 yards if using standard quilting fabric (Quilt Backing Instructions)
Batting: About 40" x 52"
