Gina came out to Wild Rose Farm for the PASA Summer Farm Tour in July to try and get some wool for her bobbin lace work. We ended up selecting about a pound of combed top which she was going to use to stuff/wrap in her bobbin lace bolster. Apparently, some of the synthetic materials (polyester?) can be slippery and the pins don't hold well enough. It sounds like it is working out really well for her. I see that the instructions to make a bolster also mention using felt as part of the wrapping ...... well, our combed top is also great for wet felting & needle felting, so it will probably tighten up or "felt" over the years with use.
