Bubble Stationery

What is bubble stationery, you might be asking yourself.  Well, it is stationery that is pretty colors in a bubbly design.

How do you make this?  It is so easy.  This one comes from one of my favorite books, The Big-Ass Book of Crafts by Mark Montano.
You will need:
Food Coloring
Writing Paper
Plain envelopes
small bowls
straws
1 teaspoon dishwashing soap
1 teaspoon sugar
1/2 cup water

Mix the dish soap and sugar into the water until dissolved.  Add food coloring, then, before stirring, put your straw in and start blowing bubbles.  When the bubbles start to form a big heap and go over the bowl, gently touch your paper to them for a colorful bubbly effect.  Repeat until you have colored your paper to your satisfaction. 
It is fun to mix colors, and to make matching paper and envelopes.
You will go through lots of food coloring - you kind of have to add more to get colorful bubbles.  But this is still one of the cheapest crafts around!
