Color fading should not occur with normal wear as the fiber has been mordanted and only dyes reputable for their fastness have been used. It is not recommended, however, to leave the fiber in direct sunlight for long periods of time.
Natural dyes are sensitive to dramatic changes in pH, therefore strong alkaline soap solutions may cause a slight shift in the color of certain dyes. Use pH neutral soap if available.
Felted fabric is created by heat, moisture, alkalinity and agitation, conditions also present when washing. Care must be taken when hand washing felt as excessive heat and agitation may continue to shrink wool felt that has not been completely fulled. Hand wash fabric in room temperature water with a small amount of gentle soap and minimal agitation.
Felted forms that have been stiffened with shellac should not be crumbled when washing. Instead, carefully subnerge the item in wash water, gently rubbing any area that is dirty, followed by submersion in rinse water.
Either place the item in your washing machine on the spin cycle to extract excess water (felted froms should be stuffed with a towel to maintain the form) or press in a dry towel. Damp 2-D felt may be ironed on the lowest steam setting, blocked (pulled into shape) and air dried. 3-D felt may be steamed (an open tea kettle works well if you don’t have a clothing steamer) to provide elasticity for reforming. Stuff the steamed from to shape and air dry.
Moth larvae feed on keratin or wool protein and are a threat to any woolen, however, seldom do they establish themselves in items that are worn or used regularly. If woolen items are not to be used for an extended period of time, wash the item and store in an airtight container in cool temperatures. Cedar, pennyroyal and lavendar have insect repelling fragrance and may be placed in the storage container to further deter moths. I occasionally implement the use of a non-toxic mothproofing agent as an additional deterrent and items treated with it are labeled so in their material and process description.
