Hi, Don! The original method I used was to use a piece of rope and use that to roll the edges of the fabric and stitch a loop around that while holding it by hand. That took a long time. The second time I used the method that Brian at Cape Falcon recommends in his videos: Running a piece of seining twine in a criss-cross pattern every couple inches between both pieces of skin and pulling that tight to cinch it together and hold it while folding it over and doing the sewing. Since writing this post I've helped do another kayak this way and we got the sewing done in just a couple hours. I hope that helps!
