Everyone has there little tool or notion that they can't live without. I am always out of these little purple markers - so I told Clint to just buy me a ton, and I won't need them for at least 8 quilts. I go through 3-4 markers per quilt. So, my little stash for just me. It's exciting to have all these markers and I won't be going crazy at the end of the quilt because I can't see my lines.
