Would you like to do something really forbidden?
Then grab a permanent marker and draw ONTO - for example - a seat cushion!
Yes - your childhood desires are finally heard!
It might only work on cotton and you should protect the backside of your work with slipping a plastic bag between the layers of your piece so the colors won't bleed through to the back. I just left the foam inside and it worked fine.
After you are done drawing, sprinkle about 10 drops ( depends on the size of your design - I used a lot more for the large "flower") rubbing alcohol onto the middle of your finished design and watch the magic evolving and spreading right before your eyes. Let dry and iron or put in a dryer to heat set the colors.
Incredible fun and super easy. I just drew a very simple design but you can experiment with different shapes and colors.
If you try it please let me know - I would love to see YOUR design!
