So I've finished off the 20 squares for my "Barn Raising" Baby Blanket and am about to start weaving them together with kitchener stitch. My question is... each square has four sides of "live" stitches with a tail left at one corner. What do I do with this tail? Can I somehow join it to the adjacent side? Tie it off? Weave it in along with the kitchener stitching as I come to them?
