I wash all fabrics before cutting them. I cannot wash precuts but I use steam for pressing . I never was allergic to
anything until my fifties when I developed asthma and began a long battle to find the triggers for it. There are quite
a few and one is FABRIC in the LQS. Washing every thing helps to keep me from wheezing when I go shopping for
fabric or clothing or when I am cutting or piecing.
None of my four children had allergies when young but each one has some problems as they pass through their
forties into early fifties. All test positive for unwashed fabrics in clothing and bedding.
Therefore I wash !!
