i made my first quilt in 1976- have made many since then- every single quilt i have made- even the 3 that have taken 'best of show' awards have been thrown into a washer- and then a dryer after i finished the last binding stitch-
even the silk and wool ones-
i ALWAYS wash and dry my quilts- especially the ones i am giving away = expecting the recipient will at some point need to wash and dry it=
if the care instructions are too restrictive chances are it will not be used- because people don't want to A) deal with it, or B) they are afraid to ruin it.
