How to calculate how much yardage is needed
Is there a way to determine how much yardage is needed for a quilt? I'm not using a pattern. I'm going off a picture of a baby quilt and making my own paper piece blocks.
I found something online that says for a king sized quilt I will need 9 yards unless the fabric has a repeating pattern. Does that sound about right? what about if there are lots of little triangles within each block? It seems like you would need more. Or when paper piecing it seems like I would need extra. Although 9 yards sounds like a lot of fabric, so I just don't know. Are there some guidelines to figure this out?
