Make an Awesome Water-Resistant Picnic Blanket From Old Jeans

Next start sewing. You will need to sew up 11 rows of 11 squares. I used a 1/4 inch seam allowance and it’s all easy straight seams. After you have 11 rows you will need to sew the rows together.

To add the shower curtain to the back, you will lay out your quilt on the floor with the top facing up. Make sure you ironed all the seams nice and flat. Then lay the shower curtain liner on top of that, with the right side facing down. Pin all around the outside then sew with a 1/4 inch seam allowance. Make sure to leave a 2-3 foot section unsewn to turn it.
