I use sheets all the time but do not hand quilt (way too hard to push needle through). I search out good sheets from the goodwill, salvation army, yard sales, etc., wash them up and trim all salvages, top & bottom hems and keep for using on my LA. If I find good flat sheets on sale in my local stores, make sure the are around 200 thread count as those don't pill as often as some in lower thread count. Your quilt...your way...
