All fabrics are washed during manufacture but due to the nature of the dyes it is possible that some light dye residue may remain. We highly recommend washing all new fabrics prior to use. This not only removes any residual dyes but also minimizes shrinkage. Fabrics can be machine washed but recommend soaking them in cold-water for an hour prior to putting them in the machine. Use cold water only in the machine. The water may pick up some color. This is perfectly normal. Please note that fabrics are color-fast and will not fade upon washing. Tumble dry fabrics until they are almost dry and then take them out and iron to prevent wrinkling.
