That said, the pattern is available both ways. So you can print out the whole thing, tape all the pages together, and use that to cut out the fabric, if you prefer. But we recommend only printing the part that you need to cut out.
You can cut the Pocket and backPocket parts out of a lining fabric if you prefer but this will only be needed if you deviate from the recommended main fabrics.
Since this is just a couple of rectangles (with a slanted side), you can just use a ruler to cut out the main part. Then you use Part 2 to cut out the crotch part. Save a tree.
