I have seen these before and thought they were for storing knitting needles but I learned through a museum curator that the long channels were used for storing embroidery floss so that it wouldn't tangle. This wonderful example has the initial M T and the date 95 (1795). The hand stitching is so hard to see that you need a magnifying glass. I don't know how they had a needle that thin or thread that fine or a needle with an eye big enough to get the thread through. 15 1/2" long by 3 1/2" wide. There are 6 channels for holding the floss and a pocket at the bottom with a thread covered button. It is a very fine linen homespun and is hemmed around all the sides. The floss keep folds or rolls for putting in the sewing basket. It isn't colorful but it is beautiful and is from the 18th C. It is in excellent condition with just a bit of age discoloration. This is a fabulous sewing accessory for putting in the period sewing basket.
