I prewashed it in hot water specifically to achieve maximum shrinkage before using it because if someone washed it in hot water after I'm dead & gone and it shrank the 16" then, totally ruining the quilt I spent a million hours working on, I'd still turn over in my grave! Hopefully they'd not use hot water, but you never know, as Betty K [above posting] pointed out!
HAPPY MOTHER'S DAY, FRIENDS!
