Many hours and Ziplocs’ 202 exactly and 7 different Co., the sorting is now done not sure if your interested but I’m going to share anyhow I love old things and when they are a part of my family I treasure them. While sorting through all those skeins I found 67 skeins that belonged to my grandma that my mama kept wrapped in tissue paper, she was 86 when she passed back in 1981, Some are from J.P. Clark one even had their 9 yard skein patent day printed on it “Wed. Dec. 27, 1921.”One from DMC was made in France it was the Mouline special containing 8 met. 8.7yds from back in 20’s, another one is from Galaxy selling for 27cents. One came from Germany from a company named Madeira not sure how far it dates back hard to read the faded lettering. Another co. is Bucilla they were just reg. their U.S. patent, one of the their other skein’s not only states it’s made in the U.S.A. but also tells you to its boil proof ( I noticed most of the skeins stated boil proof on the labels) and to “launder in Ivory Soap Flakes” and use a moderately hot iron. The American Thread Co. sold “Star Six Stand” for 5 cents, I don’t have the label with the Co. name but the skeins say boilfast on them one still has a 5 cent tag on it very worn but you can still make out the in U.S.A. on it, another one say 3/10 cents on it and the made in U.S.A.
