I prewash and preshrink all of my fabrics before cutting the patterns. Use precaution with laundering the first few washes to prevent further shrinkage and possible color bleeding, especially with darker colors or fabrics that have been custom dyed.

Machine wash warm, rinse cold in normal cycles with regular detergent. Machine dry warm. Fabric softener and dryer sheets may compromise absorbency. Warm or hot steam iron when needed.

No special care needs to be taken with PUL covered garments. Machine wash. You may want to use a cooler temperature for machine drying, but warm cycles will not harm the fabric. Avoid very hot drying temperatures. Do not iron. Do not use fabric softener.

I recommend using a wool wash rich in lanolin. Google search "wool wash" to find a variety of good products online.

For best results, hand wash in lukewarm water when the garment begins to retain a urine smell after air drying. Gently agitate and squeeze the garment in the water. Allow the garment to soak 20 minutes. Dump the water and gently squeeze out the excess water. If your wool wash requires rinsing, rinse in warm water. Rinsing in cold water will shock the fibers and cause shrinking or "felting." You can run the soaked garment through a delicate or hand wash spin cycle to remove excess water, or you can lay the garment on a bath towel and roll the towel the length of the garment allowing the towel to soak up excess water. You may need to repeat that process once or twice. Air dry flat away from sun or direct heat source. Warm steam or dry iron if necessary. Do not use fabric softener.

If your wool wash is not rich in lanolin, you will need to reapply lanolin to the wool fibers after four or five washings, or when you notice that the garment is less water resistant.  You can purchase lanolin on line or in your local drugstore.  It is usually available in baby care aisles.  "How to Lanolize Wool. . . Without Lanolin Spots!" is an excellent article with detailed instructions.
