what do you do about the chemical in the dye? I now the new fabrics probably wont bleed or shrink but I don't want the chemical to give anyone alergy Also those quilts used as demos on utube probably never get washed or used. If you bought a child a pair of pj's would yu wash the before they wear them. If i make a wall hanging that i never going to be washed then I may not pre wash it. If it is going to be wrapped around soeone then it gets washed.
And how about the shrinkage...all fabric from the same line of fabric doesn't come from the same cotton patch and finished the same. so there could be differences in shrinkage. Do you wash new sheets before you sleep on them.
Why should quilt fabric be treated any different than other fibres we put on our bodies
