The cutting instructions on page 2 of the pattern are for a quilt with 6-inch square blocks, but you'll find cutting info for 9-inch and 12-inch blocks on page 5.
The jigsaw puzzle quilt is most effective as a scrap quilt, but you can double-up and use each fabric more than once. Patches required for individual blocks are small, making the jigsaw design a perfect stash-busting quilt pattern.
I think this design looks good with a few black, or "empty," slots. 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 lights, darks, mediums, warms and cools, and be sure to add some black blocks.
