I have two ideas:
1) Use cutouts and soft pictures out of magazines to make a collage and then putting the lyrics on top.
2) Painting little watercolor pictures and putting the lyrics on the paintings.
I am leaning toward option 2 although I have no idea how I am at watercolors...hopefully good!
Here are some of the lines from song's I plan to use (I'll have to narrow it down to two or three):
"You'll be my little man, You'll be my lady, You'll be my funny little buddy, Hey hey pretty baby" -Woody Guthrie's Whose My Pretty Baby
"It went 'zip' when it moved and 'bop' when it stopped, and 'whirrr' when it stood still, I never knew what it was and I guess I never will" - Peter, Paul and Mary's The Marvelous Toy
One of each line on this one: "I've got peace like a river in my soul - I've got love like the ocean in my soul - I've got joy like a fountain in my soul - I've got love like a river in my soul" - Elizabeth Mitchell's Peace like a River
"I've gotta shake, shake, shake my sillies out, Shake, shake shake my sillies out, Shake, shake, shake my sillies out, And wiggle my waggles away!" - Raffi's Shake the Sillies Out
"I love you so dearly, I love you so fearlessly, I wake up in the morning so early, Just to tell you" - The Be Good Tanyas' Littlest Birds Sing the Prettiest Songs
That's what I've got so far. Any suggestions are totally welcome. When I have one made I'll post a picture!
