Okay, here's how it goes. It's super easy and just a little bit messy. ;)
Supplies: yarn + glue + bowl
Prep: Cover a bowl with plastic wrap. Or use a balloon as your form. (I think these look pretty.) Cut yarn into long, but manageable, pieces. Pour glue into a bowl.
Method: Dip yarn into glue. Use your fingers to squeeze off the excess glue. Place the yarn on your bowl however you like. Let dry overnight.
*Once the bowls were constructed I considered brushing on some liquid starch (just to help stiffen the yarn) but I didn't get around to it.
The kids had a fun time with this project. Actually, I should back up and give the real account. At first everyone freaked out over the glue. Once the initial shock was over Conner got into a rhythm and really enjoyed this project -- he lasted the longest and put a lot of focused effort into it.
The other two needed help from time to time. One of them had a freak-out, but returned to finish the bowl the way he wanted it and I tried my best to step back and let it be. Let it be. And it turned out just fine.
The other one loved the project, repeatedly complimented everyone's "awesome" bowls, and made a good effort until she ran out of steam and I finished the bowl. Simply because I couldn't let it be. And she was more than happy for me to help.
Bottom line . . . it kept them busy for an hour, yes there was lots of hand-washing and wiping but the mess was contained to 1/2 of the dining table (not too bad), and they all ended with a project they were proud of.
