Sheep Silk is a 50% Silk, 50% wool thread that stitches beautifully for wool applique. It is perfect for basketweave on 18 ct. canvas and on 18 ct linen for cross stitch. I have used it on 28 ct linen for cross stitch, in which it gives the stitches more dimension. All colors are hand-dyed and skeins are 25 yards. This is also a beautiful thread for wool embroidery.
