How to Make a Picnic Blanket Backpack Out of T-Shirts

Step 2 Sewing the Blocks Together

Place 2 squares wrong side together, pin one side, and sew a seam. Use a serger, or if you don't have one, a small zigzag stitch on your regular sewing machine and cut the extra fabric from the seams.

Continue connecting squares until you end up with four rows of four squares.

Now sew all your rows together and sew a seam around the entire thing.

Blanket portion of the bag, finito!
