I know we are supposed to be quilting for future generations, but really cannot find it within me to worry about it yellowing a few decades from now. I just can't see my quilts being in a museum or whatever 100 years from now and someone saying if only she had not used starch. LOL I will not give up my starch!
When making quilts, I am making sure they are washable, even the hand quilted ones. The hand quilted ones have lots and lots of stitches closely spaced to make them washable. Surely any starch would come out eventually. Plus, now days all you gotta do is add those non-chlorine bleach additives that will take out the yellow.
