Our daughters teacher had each child bring a white pillow slip.
Then the teacher had brought some paint ( not sure of what kind) - but she had each child put their hand print on every ones pillow case. Then she had them write their name across the hand print. ( they were in 2nd grade so I don't know for sure how well a a kindergarten can write :)
The teacher then wrote across the center of the pillow case the little saying " Now I Lay me down to sleep,
I'll count these hands instead of sheep
And aways remember the friends I made
When I was in Mrs. Fairbrother's 2nd grade class.
It has been one of the few things our daughter kept from the year end school parties.
I hope this helps,
