Hi ladies. Hoping someone can help me with a paper piecing questions. I have a vacation day Thursday so I'm taking a paperpiecing class. Does it normally use a lot more fabric than a standard pieced top? I just got my fabric requirements and for a twin size its 7.25 yard black then 4 pieces each of four different color familes so around 15-17 yards of fabric for a twin top including binding. Does that make sense or am I misunderstanding?
