Stuffy puffy and fluffy, and clue 4!

Doing clue number four for Allietare mystery quilt was easy and fun, and I love how the black background fabric gives the illusion that the other fabrics are floating in space, how fun is that!?! Also I am back to working on my flutterby quilt as well.

For some reason the blocks are not coming out 10.5 when done, despite me checking and rechecking and then trimming away even the most scant dusty particles for squaring up the 4 patches and recs, I don't get it. I gotta find another Jen Kingwell customer and get to the bottom of this.
