I belong to a rigid heddle group on FB. This is a great way to get fresh ideas about weaving. Suzanne de Lugo tried painting the emerging cloth on her loom with fabric ink pens, working on a neutral colored, plain weave, acrylic "canvas". She is quite the artist to begin with, and her experiment was inspiring.
So I wove up an experiment of my own, on the 3-in-1 Swatchmaker. I used wool, linen, and cotton as my yarn and created three pieces for my granddaughter to draw on, figuring if nothing else the objects could become bookmarks.
The linen worked the best, as it creates a fairly flat fabric. Cotton was a close second and probably would work better with a tighter weave. Wool was too fuzzy to work on.
I thought it might be fun to weave up some linen or cotlin towels for Nora to draw on and color. However, her interest in this activity waned rather rapidly. I keep trying to encourage her craftiness but so far no luck.
