I'm waiting on my supplies to arrive, and am anxious to make my underquilt. I want to make 6 foot full 3 layer quilt. My question is should I make the darts longer than 12''? I was thinking 18''. Also should I add some darts on the sides so the quilt won't sag in the middle? I want to end up with a quilt 6 ft x 45, or 48 inches. any suggestions?
Going to 18" on the darts should work just fine, especially with the longer quilt length. Side darts are a good idea. That's how Mac does his designs. I haven't done much with side darts, but I can't see any big negatives.
