You can find a lot of fun things at the dollar store to use on your art work. On my last visit I bought some packages of erasers (5 to a pack) for a dollar. I practiced carving stamps with them.
Hand carved stamps
I stamped all over an 8 x 11in. sheet of paper using all the design stamps with different ink colors. Then I did some doodling, added rubons and stamped a few words. From this orignally designed paper I made a small pamphlet journal and a greeting card.
