FLYMPH FORUM

I thought I read somewhere about a year ago that Semperfli was copying Pearsall's colors. At that time, they had only a selct few colors in production, but now they have quite a few colors. They call it Nano Silk.

They also have a substitute yarn for Chadwicks 477. I just received two cards.

I think this is the Semper Fli silk product interesting product description stating they match E&L colors from an actual vintage copy. Chasin’ the Grail.
