I don't know about the plants, but oh yes they will get into trouble in the sewing room. Anything small and shiney will attract them and they will probably eat it. It's not too big of a problem if you keep her out of your sewing room or keep it very clean. I'm thinking my sewing room and even my cats didn't want to go in there. Too messy. No cats anymore, but I do miss them. Just remembered a cat I had several years ate a tuber from an English ivy and almost died. The plant was gone but the roots were still there. I learned to research any new plants after that.
