Hey Meghan - I have a few hand made knitted yamalkes (kippah, skullcap) that I wear all the time. They're getting a bit dirty from daily wear and I was wondering if you might have some advice on cleaning them. I'm not sure about laying them flat since they are "shaped" (at least to some degree) since they worn on the head. Any help would be greatly appreciated. *I can send you a pic of one of them if you think it would help
