When I started using the Setacolor Fabric Paints from Pebeo a while back I tried them on different fabrics to see what the results would be like. You can see here how they looked on hessian, denim and faux leather - I'm really pleased!
I painted a freehand leaf shape on the faux leather with Olive Opaque (83).
Then I added some Cinnamon (93) and Brick Shimmer Opaque (63)
Next I added more detail with Chocolate (88) and White (10)
I used Raspberry Opaque (81), Oriental Red Shimmer (64) and Purple Shimmer (65) with Olive opaque (83) for the Rose on denim.
I used Buttercup Opaque(13) with Brick Shimmer (63), Chocolate (88) and Olive (83) for the Sunflower on hessian.
