Step 1: Cut out your fabric
You'll also need a sewing machine.
(I also let my daughter decorate the fabric to make blocks for her cousin--this step is optional ;)
Step 2: Sew the first 2 pieces together
Ok, so to do this, stack your pieces of fabric good sides together with the edges lined up. You can see in the photo that I drew a line to show exactly where I needed to sew (this is just for the tutorial--you don't need to do this). Plant the needle 1/4 inch in from the edge and take a few stitches. Back stitch to lock the threads and continue stitching all the way across the project.
1/4 inch from the end, plant your needle and back stitch again.
