I am just finishing up the plans for a ~10 deg down top quilt.
I guess I am getting a bit tired, because all of the sudden I am wondering if I need to include a differential in the chamber size for top quilts. (example: 5" spacing between the baffles on the inner shell and 5.5" spacing on the outer.) I know on my UQ, this really allowed the chambers to loft out, but I can't for the life of me reason my way through this for a TQ
I am planning on a 3" loft height using a 2.5 inch tall baffle, and would calculate fill as 3" X length X width.
My crude representation below - no differential on left, differential on right. I was planning for no differential, but all of the sudden I am locked in an indecision loop.
