Summer Craft Camp Ideas

So I'm thinking of hosting a craft workshop during the summer for my daughter and her friends. I'm calling it, Summer Craft Camp. Original I know. Problem is I'm lacking ideas. I have a few but I need more.

Here's where you guys come in. I need craft ideas that follow these guidelines:

1. Geared towards 7-9 year olds
2. No use of foods as many of the kids have food allergies
3. Low budget
   
4. Must be fun!

If you can suggest some great craft ideas for my kiddos & friends, please add them to the Linky list below. Just click on the "Click Here To Enter" link.  By the way, the easiest way to add a picture is to click on the "Web" option.  You'll get list of images from that particular link for you to choose from.
