I have hand knit this hat from the kit. The hat is acrylic, machine wash and dry with the Lamb pom removed. Lamb Pom ties on with a satin ribbon. Easy to remove and put back on. I say hand wash pom gently if necessary. These are from kits from DMC yarn company. The kits retail 15.00. I am charging 25. For the hats. So you are paying 10.00 for my labour. This for everyone who can't knit but loves this kit! If you knit the kits are available at Michael's, Zulily, and other online shops.
