hey rainbow-

this sounds so cool. my T does art therapy too and has lots of "stuff" in her office to use.

even if you dont have a big picture, remember you could do other creative things to indicate that "the area" on the collage is your mom. for example, you could glue the little picture on another sheet of colored paper and then write your mom's favorite things around the picture or you could write characteristics of your mom around the picture....this way the space is still "your mom."

See?.. something like that.

good luck. don't stress -- it is supposed to be "freeing"
