4- With right sides still together, fold blanket on the diagonal (seams created to attach the two pieces will be together with the smaller piece on the inside).
5- Using an Omnigrid ruler (or similar) create a 90 degree angle on each corner using the folded edge as a base and the stitching as the top. Mark well and pin. Stitch along the marked line. Repeat on all four corners
6- After completing all four corners turn blanket right side out. Check corners for accuracy, holes and tucks.
7- Turn inside out again. After you are sure the corners are correct, cut off excess fabric from each of the 4 corners.
8-Turn blanket right side out again. Straighten all seams, lay flat and press.
9-Carefully pin around the entire seam connecting the two pieces of fabric together.
10- Sew around the seam (stitch in a ditch) be sure to carefully close up the turn around hole. I recommend using a zigzag stitch or a decorative stitch of some kind to add detail and hide any out of place stitches.
11- Congratulations! You have completed a self binding receiving blanket!
