Lumi’s Inkodye Photo Fabric Dye Kit uses a dye that develops photos on materials like fabric or wood when exposed to sunlight. You can use negatives or even small objects to create images out of silhouettes. Paint the dye on, put a negative or silhouette on top, and place it in the sun. The UV light develops the film on the material, and next time you’re out in the sun you print will change colour in front of you.
The dye comes in 3 colours so you’ll have to mix if you want other colours.
Available from Lumi for $11.95 per 4oz bottle.
