OK, if you really would like to give this and want to make it as good and durable as possible, go to a copy center like Staples or OfficeMax and have it printed in color on No-Tear paper. It really is the best; it costs about $1.50 and is worth every penny. Also try to find some thin vinyl (re-purposed) rather than card stock for the backing material. I have not tried it yet but hot laminating with 5 or 10 mil and cutting it at the copy center would work nicely, I think.

There are many options for making the 2 hinge points. Grommets from paper crafting work best but require thin cardboard stock and grommet tools that may not be available to many. Rivets work well too but care should be taken that beating them into submission does not mar the face of the GuessEstimator.
