This how I'm doing my differential cut Costco underquilt with faux baffles.
- First I ripped the longitudinal seams and left the transverse seams
- Then I turned the quilt by 90°, so that the trans chambers are now 60" long longitudinal chambers
- I need to reduce the 70" width to a more reasonable 42".
- To do that I am marking 1" each side of the seams and pinning the two chalkmarks together
- Then I am sewing a raised seam, this gives me a slightly less than 1" baffle and reduces each chamber to 3" on the inside and 5" on the outside (differential, YAY!)
