Potato Starch Resist

In case anyone is interested, I also have a recipe for a potato starch resist, a little simpler than the potato dextrin resist.

Potato-starch Resist
This recipe can be doubled or quadrupled. I was able to cover about half a yard of fabric with this amount.
2 3/4 cups water
1 cup instant mashed potato flakes
1 1/2 Tablespoons of liquid starch (the stuff in the laundry section of the grocery store)

Bring the water to boil in a large saucepan. Add the potato flakes and turn heat down to medium or low. Cook, stirring by hand with a large spoon, for 5 minutes. Remove from heat, transfer from your kitchen pot to a small bucket (I use paint containers from my local hardware store). Return your pot and spoon to the kitchen. Add liquid starch to the bucket, stirring by hand with a large whisk (do NOT use this whisk in your kitchen anymore after it's been used for art work). The mixture should be very smooth. Let the mixture cool, then spread it on the fabric. I put a piece of plastic wrap on the potatoes while they cool so that they don't dry out and get crusty on top. I used wide plastic putty knives to spread the starch. The thinner the layer of resist, the finer the network of lines you will get with the dye.
