Sometime in the 1990s, Threads become an all-sewing magazine. Before then, it was mainly sewing but included other textile arts such as lacemaking, weaving, knitting, etc.
Can you tell me the number of the first all-sewing issue? It would probably be the first issue that said “For People Who Love to Sew” on the cover. Then I would know which issues to buy on eBay. (Sometimes the only information given is the number–no mention of contents and no picture.)
