I wanted to change the appearance of this camouflage-like fabric.
I took a letter texture plate used for polymer clay and did a rubbing with Caran d'Ache Neocolor II watersoluble wax pastels. The effect appears very subtle. If I'd used a more contrasting color, the letters would show up more.
For this rubbing, I used Shiva Artist's Paintstiks- an oil-based fabric paint. It's very messy and harder to rub the lines on the fabric from the texture plate. I like the pastel colors. This sets with heat and becomes permanent.
