Heh, here's a coupla tips for FREE...
Okay, washing jersey inside out is a start. But do this, also...wash in COLD water, GENTLE cycle. Don't wash with anything else. Shake out and put on hanger until dry. If you put it in the dryer, use LOW heat/damp dry, (approx. 15-20 min) take out immediately and hang. Under NO circumstances use high heat in the dryer...it will weaken and destroy the screenprinting!
Also, use a liquid detergent not powder. WOOLITE is good, and there are others. Hope this helps.
