To save you from scrolling, here is the picture again of the original pastel-dyed yarn followed by the same yarn overdyed brown, black, and burgundy, respectively.
A rigid heddle loom as only one heddle. However, you can use a second heddle (if your loom is so designed) or a pick-up stick to expand your design possibilities. I went with the pick-up stick to create a pattern with weft and warp floats. (Weft being the horizontal yarns and warp being the vertical yarns.)
For my project, I used the burgundy yarn as the warp and black yarn as the weft. For you weavers out there, the pick-up pattern was two under and two over. I think it turned out really well and I like the contrast of the two colors.
Have a great Friday! Don't forget to look for the fiber artists at your local farmer's market tomorrow!
