A soft (can be rolled up), beige silicone mat to practice face painting techniques on. Paint the motif and take a picture of it for your example book or use it only as an exercise.
I have tested the carpet by painting motifs with all colors, especially the""hard to wash""black (dfx), red (PXP) and turquoise/green (superstar). I painted on the colors and left them on the carpet for 24 hours. I then washed with water and detergent and a dish sponge (with white scrubbing side). The carpet had no discoloration after washing!
