I save and buy all patterns/sizes of blocks ... and eventually make various
size tops by adding fabrics if needed so that all blocks end up one size,
usually 12" square. Then will take a coordinated fabric and do 3" sashings
around all blocks, plus a cornerstone, and an outer border. You might
call these Memory Quilts, as blocks come from many sources, and some of
my own "orphan" blocks from other projects.
