I am doing a PP BOM and having trouble.
One thing I read in my quest for information is use pins to mark where ends of seam are. You would put them straight through just to mark and hold in place. Check the middle of the seam. If everything lines up, points meet, etc, hold together with a plastic coated paper clip instead of pinning because pinning will distort, especially smaller units.
I am going to try this on the next block. I believe my seams are distorted from pinning. I did a quilt of 12" PP blocks before and didn't have much trouble but didn't have tiny pieces and multitudes of points and things to match. The BOM I'm doing right now has a ton of little things that need to match up perfectly and tiny tiny pieces and units and I can't seem to match anything!😬
