People like to use stamps for lots of reasons. One of those reasons could be to make a patterned design as a background image for a paper project. Sometimes the stamp you'd like to use has a restriction against using it on items you want to sell. The best way around that restriction is simply to make your own pattern stamps. But how, you ask...
Well, there is a neat product out there called Sugru. It was developed to be an easy to use plastic type product that could be used to either mend something broken, or create something from scratch. Here's the website so you can read about it and see some examples: http://www.sugru.com
You can buy from their website or Amazon, among many options for buying Sugru.
On one of my favorite "maker" sites, Instructables, I recently found directions on how to use Sugru to make your own pattern stamps. The instructions include a seamless pattern on a roller you can use to cover a whole sheet of paper easily. Here's the link to the Instructable: http://www.instructables.com/id/Impressed-Sugru-Stamps/
Hope some of you find this information useful.
