I have carefully put them in stacks and then into sandwich baggies. The units in each block are only 1 3/4" big when sewn together. The block will be 4 1/4" big unfinished. These cut pieces are laying on the top of a Sterilite tub. See my earlier story: http://quiltcrazie.blogspot.com/2013/10/design-wall_28.html.
Have a good evening. Time to make dinner,
Yours in quilting,
