DLTK's Crafts for Kids
You are my sunshine craft
You Are My Sunshine Craft

I've had a lot of positive response from people about this craft.  Although it was originally made for mother's day, here are some alternate ideas I received from people who used the site:

The depressing thing about Mother's Day crafts is that I likely won't get the ones I design and I really want my kids to think up something like this one for me!  Although meant to be a fridge magnet, if you don't have magnet backings, don't worry about it too much.  Use the craft for a card, make a collage/picture from it or just as individual pictures to hang up.  I'm sure mom will love it no matter how the kids present it!

WORDS TO 
"YOU ARE MY SUNSHINE"
PLAY MUSIC

You are my sunshine
My only sunshine
You make me happy
When skies are grey
You never know dear
How much I love you
So please don't take my sunshine away!

(substitute the word Mom or Grandma for the word DEAR in the third last line)

There are more words to the song, but this is a good length for younger children.
