Blocking a finished block to enlarge it or shrink it
I understand that one can TEMPORARILY change the size of a block/unit by blocking it.
What happens when the item is washed and the fibers revert to their "normal" length?
Think/Remember - the old denim jeans that we had to wear for a day or two before they were more comfortable and stretched out. Every time they were washed and dried, they reverted back to their "normal" size.
Especially if the unit is NOT quilted to a stable batting - - - - which some say will stabilize a block.
