This is Leaflet No 2231 from Woolco. I'd say early 1950's. The pattern gives directions for the pictured rug worked in Carpet Warp. And, there's the thought. What is a comparable carpet warp to refer to?
Let the Google searches begin!. Now, I learned that January & Wood Company, now defunct, but previously makers of Maysville Carpet Warp, also produced for carpet warp under the brands of Southern States, Ace Hardware, Kroger, K-Mart, Coats and Clarks, and ... you guessed it ... Woolco.
Which, now knowing the equivalent brand is Maysville (named for the town of the January Woods factory), I headed over to Ravelry for additional specifications on the yarn.
I hope this is enough information to get one started, because I need to get back to work now!. Oh, I've listed the Woolco Rug pattern as a Free Download, should you like to give it a try.
Thanks for dropping by,
