Hi....I'll explain what I did.
The poster on post #2 posted a link to a picture. DISer "nkjzmom" made the t-shirts in the picture. She also gave directions. It really is easy. I made the shirts on Saturday. They look exactly like the ones in the picture.
When you click on the link to the picture, you'll also see the directions.
I got the same paint kit at Michael's that nkjzmom did...TULIP Spray on Fabric Paint (4 pack).
I also bought a squirt bottle there for $1.50 (in the Wilton candy making aisle).
After the flour/water mixture has hardened, spray one color over the mixture.
I let it dry & then sprayed another color on the outside of the first.
That's how I got 2 colors.
I did let my dry in the sun. I had to wait 3 weekends before I got a warm, sunny weekend...but you can let them airdry.
The original directions to make shirts with the flour/water mixture are in the Family Fun July/August 2005 issue (but nkjzmom designed the Mickey heads herself).
The shirts look terrific!!
