Hello, I have a question about using felt for goldwork and embroidery in general.
I want to make sure my felt is acid-free as it will be placed under white silk and I don't want the silk to yellow with age.
Do any of you know if the craft polyester and/or acrylic felt at craft stores is acid-free? There is no indication on the packaging. A more expensive option is wool felt, but I can't find any information on whether or not that is acid-free either.
Any help is greatly appreciated! Thanks!
