Carolyn Ambuter's The Open Canvas, which explores various 'pulled weft' and 'pulled warp' embroidery techniques. The diagrams of needle paths are very clear, and many of the techniques could be applied to warp and weft and hems while stretched on the loom. We can plan ahead, and instead of removing warps and/or wefts from a woven canvas, we can leave them out while we warp and weave. ISBN-10: 0894801716
