I would try the spray basting to get it quilted then washing it several times in a no-dye, no-fragrance laundry detergent before giving it. This will take out the chemicals that are the issue....washing twice would probably do it but just to be safe, I'd do it 4-5 times. After a bazillion years of quiltmaking, I can't quilt and get a good result any other way than spray basting.
