I planned my weaving on a woven piece that was so uninteresting I relegated it to a scrap. This gave me the dimensions for the new piece. And it allowed me to play with various stems of rose hips to get a composition I liked and that would allow me to use the supplementary purple warp to attach the stems. As I wove the new piece, I unpinned the stems as needed and wove them in. It also helped that I’d taken a photo of the composition so I could replicate the placement in the new weaving as I went along.
This photo is of the woven piece. The color is more like the top picture.
