Love this weaving pattern. What a great fabric craft! You could use about any pattern of fabrics! The article I believe is in spanish but the pictures are pretty clear so I think you can try these patterns by using the pictures as a guide!
Couching is simply sewing a heavy thread in place with a finer thread. Its a retro technique, too, that was originally done by hand, but it works beautifully by machine as well. I use a zigzag stitch to secure the heavy thread in place.
