Ok, so I've got the liner side of my UQ cut out, I've sewn one side of the baffles to it, and I've got the side-strips sewn on as well. I will attach the baffles to the outer layer starting at the middle and working outward.
But when all that's done, what's the best approach to sew up the perimeter of the outer layer? Because of the baffles you can't turn the thing inside out after sewing a felled seam. Or is there a way to make the felled seam from the outside?
