On ours, I used grosgrain for the draw cord channel and it is kinda stiff. It doesn't really close all the way. I think if I did it again I would just use more of the same fabric to create the channel and reinforce the openings with grosgrain. This way it would be softer and easier to get closed all the way. I used Velcro to make the foot box. I like that we can use it flat when we want to.
