The Spools block is our July block. It's not difficult, but the small Spools units will reward your patience. If each spool is pieced carefully, the full block will go together easily and its size will be accurate.
As we hit the home stretch on our 26-month Block of the Month series, the Spools block -- along with the up-coming X and Z blocks -- are designed to help us use up small pieces of fabric we've used in other blocks along the way. This isn't simply thrifty; it will also help pull our final projects together.
You can find the pattern for the Spools block here.
