Currently, on the QuiltArt list, there is a discussion about scrim and cheesecloth and dyeing, so I thought I would post some photos. Below is a small sampling of the scrim and cheesecloth that I have dyed. It takes the dye very well --- both Procion MX dyes and natural dyes.
This photo (below) is a detail shot to show the difference in the weave of cheesecloth vs. scrim. The top purple cloth is cheesecloth, while the bottom green cloth is scrim.
