Please test all fabrics prior to garment production. If you have any question, please don’t be afraid to email us! We love fabric and sewing, but because of the large volume of fabrics, we haven’t been able to work with every fabric that we carry. Foils should be hand washed separately, cold water, mild detergent. No chlorine bleach. Lay flat to dry and do not wring. Do not rub fabric together. Do not iron or dry clean. Please test for chlorine and sweat sensitivity. Wash immediately after perspiration.
