how to make your knits smell better you mean? If so.... Febreeze always works great, I find. Also, a cycle in the dryer with a scented dryer sheet or something.
The dryer sheet idea is wonderful! I use them in all of my yarn bags because it keeps my cats from making a mess of my yarn plus the knits always smell wonderful.
You can always make a fabric bag (cheesecloth woks even better) filled with dried lavender, chamomile flowers or roses. Incense sticks tucked in among them are nice too. Just make sure you use the natural ones..Peace...OmGanesha
