I'm a new weaver and I am about to warp my first project on my own using my new Schacht Flip Loom. I've previously woven with a 4Harness Floor Loom (about 6 projects now). I'm having trouble finding out how much loom waste I should add to my warp length for my RH. One piece of info I have says to plan for 24"of loom waste (so for a 72 inch scarf, I would need 72 inches plus 24 inches waste plus 14 inches (20% total 10/10% each) for shrinkage & takeup or 110 inches total. This seems like a lot of loom waste to me, since my floor loom only needs about 30") and I thought RHs had a lot less loom waste. Can anyone advise me on this? Thanks!
