I put the swatch through at least three times, and it still didn't completely felt. It just got really fuzzy, but the stitches were still showing. I finally decided I was wasting too much water and just decided to start making the crown.
I felted in on hot cycle, cold rinse, with a pair of jeans. I did use regular detergent, and then read somewhere that it's best to use dish detergent. Any tips you might have would be greatly appreciated.
