Prewasher here because the chemicals really do take my breath away! Recently, fabric I ordered on-line arrived smelling so strong that I couldn't be in the same room with them until they were washed. I have COPD but most fabric doesn't bother this much. I have also had fabric bleed. I bought a beautiful red print to make a quilt for my oldest DGD but it was still bleeding after 5 washings and I will never trust it to be used in a quilt.
