OK so i'm moving on to my newest project, the all important underquilt. i really like the look of the karo step quilts so that's what i'm going for. ive got me some fabric on the way and just wanted to put my basic plan past all of you much smarter people too see what i'm missing.
basically i'm looking to build this https://youtu.be/lhVgUGx0xAM
utilizing this basic walkthrough
so for my dimensions im looking at a final quilt 60 inches long by 45 inches wide with 1.5 inch baffles. the boxes will be 9x10 with and extra 1/2 inch to all sides for the outer shell. my main question is what lof should i be looking for to get a 30F quilt? reading around it looks like 2-2.5 inches of loft should do it. imputing the numbers into the underquilt calculator and the karo step calculator i looks like i will need just under 7oz of 800 fill down, does that sound right, and will that get me where i want to be on a karo step design? any input is welcome
also a quick thank you to everyone whose info, and resources i'm using here. i think id be lost without all the shared wisdom.
