You have my sympathy. I just spent 5 miserable days feeling itchy like bugs on me from head to foot. I ate benedryl and avoided my medications, and foods, only to discover I was piecing with old fabrics from my mother's stash. It must have been the dye or the dust. All better now, but machine washed the quilt top and rinsed with baking soda in the water. All is better now. Good luck.
