First an idea about the tapestry is turned into multiple sketches.
A final sketch is chosen (upper image).
The yarns are selected based on the colors in the sketch.
Finished tapestry: lower image
I use Scandinavian yarns because of their quality and the wide selection of colors.
Warping the loom - I use cotton seine twine for warp, the vertical threads on the loom. The closer the warp threads are to each other, the finer the detail in the final tapestry. I usually set up 8or 10 ends per inch (epi).
The cartoon is a full-scale black and white drawing or printout to be used behind the warp as a guide.
