so I first matched my hexagons and did a little sewing on the line making sure that I didn't go into the seam allowance, take a couple of extra stitched in the same spot right on the corner to reinforce it a little so when you pull on it it won't come apart, you can go over a stitch or two but don't leave it short or the odds are that you will have a hole when you are done, Press your seams open.
