Having made several t-shirt quilts, I have always had good luck and have never had a problem with t-shirts being heavily scented. (Note: I have industrial allergies and perfumes and the like really bother me.) My latest group of t-shirts arrived about a week ago and I have washed them at least 3 times utilizing baking soda, borax, vinegar, sunlight and just leaving them out in the cold. Nothing is helping.
Tonight I started cutting them apart and fusing the backs. As you know that calls for the iron to press fusing. Obviously, the heat made the smells worse.
My only recourse will have to be getting a face mask and sewing and quilting as fast as I can. :( Something I will not enjoy because quilting is my hobby and something I take pride in designing a unique quilt.
Any suggestions would be greatly appreciated.
