I did use the "like Omni-Tape" product from Quest. It is quite soft and holds well. I had debated about the center drawcord, but it was the right choice. And frankly it was easier too. I attached the channels before sewing the quilt layers together, which means that the top and sides of the channel disappear into quilt seams. John described this to me and it worked well. The shame is that after making those two I'm getting the hang of it and want to make a couple more!
