We made these easy and cute owls the other day. They were made with the things we had on hand...toilet paper tubes (I even cut a paper towel tube down to size when we ran out!), construction paper, muffin cups (we used two per owl), tape, and glue. Even my 2 1/2 year old could do most of it herself! I admit they would have been a bit cuter with some brighter muffin cups. This is where we got the idea from: http://www.parents.com/fun/arts-crafts/kid/give-a-hoot-owl-craft/
To make the "vase and sticks," I took a half-pint jar, some sticks, some crumpled paper (stuffed inside the jar to keep the sticks standing up), and a piece of construction paper taped to the outside.
We shared the arrangement with Grannie & Mimi's office. The girls kept a few owls to play with. They've been begging to make more! Looks like we'll be buying some more muffin cups and continuing to collect some tubes so we can make another arrangement!
