I'm going to make a 2/3 length radial quilt. Roughly 48"x54" with 2" or maybe 2.5" baffles. I understand the concept of differential cuts, but I'm not sure how much detail needs to go into the process in order to make a quality quilt.
The inside layer (touches the bottom of the hammock) will be 48"x54" (ignoring seam allowances). The outside layer will need to be bigger in both dimensions in order to accommodate both side-to-side and head-to-foot curvatures. The baffle height will be the primary factor in determining how much larger the outside layer will be. That I don't have issue with, besides it gives me a chance to use Trigonometry again**.
What about the baffles? Do I make the outer edge longer than the inner edge in order to compensate for the head-to-foot curvature? What about baffle spacing? If I put baffles every 6" on inside layer (7 baffles for 8 chambers), I think I'll have to compute the spacing I'll need to sew them to the outer layer since the outer layer will be wider than the inner layer, correct? This will result in slightly trapezoidal shaped chambers.
One more thing, which color should be the inside? When I made my top quilt I put black in the inside and a lighter color on the outside. Should I do the same with the UQ?
