Thought I'd rally the DIY minds on a conundrum that I am having with my UQ project. I'm trying to decide on how to finish the channels on my underquilt and wondering whether or not to finish the channels using grosgain for added support. for those that have used M50 so far, what have you seen from it as far as durability? and as far as channel designs go, does anyone have any close in pictures of the channel design? I was thinking of taking the unfinished corners, and folding the corners like a triangle into itself, and then fold the channels so there is adequate opening for shock cords and clips and such. this will be a 3/4 underquilt, so the long sides will have shock cord runners.
