I purchased a blue knit wool highland bonnet about ten years ago from a now defunct comapny called H&H Scottish Imports. I wanted it to be accurate to a late 17th c. era bonnet and had read that the early ones were quite large in diameter. So, I had the bonnet made 13" in diameter. Well, I underestimated how large a 13" diameter is. It's big; real big. It's so large in diameter that I've never really worn it outside of a ren fair. Is there any way to shrink it down? I washed and dried it in the washer on hot settings and it's still really large. Would boiling it help tighten the fibers? Can I felt the wool to make it smaller? Any advice would be appreciated. I'm willing to try anything because I'm not going to wear it as it is.
