What wouldn't my daughter hide in the pillow! She'd hide everything in there that she currently hides under her pillow: books, dolls, Barbie clothes, string, etc.
I live in the Northwest, and I love that we have EVERYTHING! Forests, ocean, lakes, mountains, deserts, etc. One of my favorites is seeing Mt. Rainier on the horizon. It looks as if it's floating above the earth. Beautiful!
