Maps are great for using when you travel or just to look at and dream. Our son is a big fan of maps and the outdoors, so when it came time to create his birthday party invitations, it was only natural for us to incorporate maps in the design. We created our own invitations using Adobe Illustrator and some card stock paper. Then it was time to create the envelopes. We are always looking for ways to reuse materials, so it was only natural that we would use pages of maps from a beatup atlas to help create the look.Using an old envelope as our template, we cut and pasted and  folded, and created our unique envelopes that are sure to attract attention. We think they turned out great.
