These were purchased with the idea that they would hold felted plants as part of a kit. That idea hasn't come to fruition yet and the supplier that they came from no longer exists, so these are up for grabs. They are nice cotton canvas and could be painted on, stitched on, or yes... felted on! Or of course they could be used as-is - they are quite cute.
Cotton canvas is harder to poke into than our linen fabric or prefelt, but is still do-able. Picture 3 shows the beginnings of a felted picture on one of these plant holders.
