Someone mentioned making kits. This is what I do for my donation quilts so I always have a few ready to sew quickly. On other quilts I may cut ahead, but I NOW always make up a sample of the block or blocks so I know what fabric I intended where. Ask me why I started doing that! I cut out a king sized quilt with fabric I had been saving for ions and then when I got to the sewing stage I couldn't remember what went where esp since many of the pieces were very similar sizes, but differed slightly in # needed. It was a nightmare and took me several days to straighten it all out. Believe me I did not save time having that project ready to go. That poor quilt must have had bad mojo because I made several really silly beginner mistakes in the piecing and now the longarmer I used has had it for weeks because she is way behind.
