In reply to Tom Mahalla.

Depends on the imprints you want. Silk is fabulous, but sometimes you want something "grainier" and the only way to go is cotton. Most of my machines have nylon, but I do have some spools of cotton and silk for those special occasions. Because of the expense, it's getting harder to get silk in bulk reels in the US. Charlene Oesch at Baco died in May and Theresa at Fine Line has quit carrying silk because of the expense.
