Mother's Day Thumb Print Heart Keychains!

For the last several years, I have made thumb print heart key chains with my first graders for Mother's Day.  At first, I used clay, but now I am using wooden heart cut-outs.  I found the cut outs {HERE}.  

I put paint on the kids' thumbs and have them stamp one on each side of the heart. 

After they are dry, I add the key ring.  I found the key rings {HERE}.  We'll attach them to the poem and that's it!  You can find this poem {HERE}.
