I always keep a collection of new and vintage stamps nearby to mix and match. Mixing the stamps works especially well when I'm sending a letter with some pictures or other goodies that requires a little extra postage beyond a single stamp. Plus it's one of the easiest ways to fancy up your mail.
I stocked up on stamps earlier this week, including a book of the newly released Songbird stamps. These are some of my favorite stamps to be released lately and perfect for spring time mail.
