This started out as a Thank You card for a nice lady at my local stamp club who gave me these wonderful alphabet stamps and a set of "doodles". (See the photo hinge I turned into an exclamation mark?)
I mounted the letters on a large acrylic block, and made many prototypes before I got something I liked. Then I made a few extras for swap cards for the ladies at the club. One layer cards are hard to get right, but easy to execute once you like the design.
