I need some help on this - I've searched around quite a bit but couldn't find the kind of instructions that I need. I've finished sewing in the baffles on my first UQ, and I'm left with 3" seam allowances all the way around. I'd like to have a nice neat corner with grosgrain tie-outs and easy access to the shock cord channels (all the way around). I want it to look just like my JRB UQ. But I've studied that and can't figure out how they did it. I would appreciate some clear cut instructions on how to finish this - I have very little experience with the sewing machine - much less with technique.
