Lauren...the new tapestry looks very good! About the short ends your husband brought home--those would be PERFECT for rya knots. That's a pile technique that's done as the piece is woven. The knot is similar to what's used for latch hook but you'd create the "canvas" as you weave. There are several passes of weaving between rows of knots. It's described in several books or I can show you more about it. That small out-of-print book called Step by Step Weaving shows the method (that's the book from which I printed the continuous warping diagram). Peter Collingwood's book, Techniques of Rug Weaving also shows how to do it.
