The general purpose of adding material over the foam, as I understand it, is to make the pillow last longer. Most of the domed polystyrene pillows I've seen that have a layer of felt under the cover have a fairly thin layer - the type of felt you buy in squares for craft work, rather than the thick carpet underlay type. The cover also helps reduce the noise of working on polystyrene, but I'm not sure if ethafoam is as noisy to work on. The more layers you use, the greater the amount of fabric you will need to buy, and probably the finer fabrics are going to be more expensive, so think about whether cost is an issue. The only other comment I would make about using wool is that as a fibre, wool holds moisture, which is useful for warmth in clothing but could cause corrosion if you use steel pins, live in a damp climate and don't finish projects reasonably quickly!
Jane partridgemous...@live.co.uk > From: hottl...@neo.rr.com > > Hello All! I thought I knew what type of wool to buy to cover my foam roller but now I'm not so sure. My plan was to use wool felt: 1) because I have more than one source & 2) because I applied wool felt to my IOLI $5 foam pillow last year & it worked like a charm. When I say wool felt, I am referring to "fulled wool" that is typically used for wool embroidery, penny rugs etc. Not too thick but with some body. While wandering about the internet today, I found wool flannel & wool challis. - To unsubscribe send email to majord...@arachne.com containing the line: unsubscribe lace y...@address.here.
