First I made the cookie jar. I covered an empty oatmeal container with construction paper, even cutting a circle to cover the lid. I cut a slit across the lid after covering. Then, I printed a cute label from Martha Stewart here. I enlarged it to 150%. And I found a vintage cookie label here and also enlarged it.
Then, I found an online photograph of an M&M cookie, blew it up to the size I wanted and printed 26. I didn't save the link, but there are tons of cookie images on the web.
I found the alphabet letters I wanted. I chose to do uppercase on the front and lowercase on the back. I glued the letters on with a glue stick and laminated the cookies. The girls love sliding them into the canister through the slit on the lid!
