Comp books are good, inexpensive journals. You can find them at dollar stores, and at almost any store that has a school supply or office supply aisle. I buy them when the back to school stock up season hits, when they're plentiful and cheap.
The minus to comp books is that the paper really doesn't lend itself to many wet art techniques. If you like to paint, a comp book journal may not be for you. I tend to do a lot of gluing, so background paper doesn't matter much to me.
OK, to make your own covered comp book, you'll need:
A composition book
Patterned papers or a gift bag for the cover
Colored duct tape - I found mine at Wal-Mart, but some hardware stores now carry this as well
A glue stick
Fibers (optional)
Rubber stamps, inks, embossing powders (optional)
