I started to pick up the papers in the sewing room, but got side-tracked by a Gohn Bros. catalog. They gots work denim!! The information isn't of immediate use, because I still have enough of the superb herringbone the worn-out pants I'm wearing were made of to make two more pairs of jeans.
I got my copy of the catalog when I bought a pair of socks, but they have a PDF of it on their website at gohnbrothers.com.
I hadn't been looking at the fabrics carefully, because I ASSumed that everything was either quilting cotton or perma-press -- six bolts on a whole wall of fabric don't jump out at you.
And when I counted the weights of cotton denim, I noticed that they have black polyester double-knit to make my slippers from. But I won't be up Middlebury way until May, when Bonneyville Mill opens for the summer.
