This is the result of today's session.
Many systems for cutting scraps exist--one that many people follow is Bonnie Hunter's. You can find her ideas here: http://quiltville.com/scrapusersystem.shtml
Another good system is found in the book Scrap Therapy by Joan Ford.
I find that these systems, while full of great ideas, don't really address the sizes that I use most, so I cut 7" squares, 5" squares, 3.5" squares and leftover strips for string quilts.
- I use 7" squares when making HSTs--they are 6.5" after trimming, so four of them sewn together create a 12.5" square--a very common size of quilt block.
- The 5" squares can be used in charm square patterns or can be used to create 4.5" HSTs.
- The HSTs created from 3.5" squares can be trimmed to 2.5"--another very common unit in quilt patterns.
- Leftover differing width strips are great for string quilts.
These are the sizes that work best for me--you may find others that better fit your quilting style. Some people prefer to wait and cut as they create quilts, but for me, the organizational benefit of cutting my scraps is important--I like order!
