Clearly, it's the best choice...
It's time for some vellum mail! I think that this cartoon art was found in an old literature book that I tore up for mail art. I love using the Super Hero stamps to carry the cartoon theme through.
Here is a view of the back. Lots of confetti and glitter confetti, and of course plenty of odds and ends to make for some interest.
I enjoy writing my letters on graph paper. I like the causal feel and of course the lines are always a help! On this letter, I found myself doodling in the margins and where ever I had a spot. It's a great way to show your pen pal some new stamping ink, or new washi tape, or just a random sticker.
These A7 envelopes are called: "Parchlucent"...they are technically not vellum but very similar. I really can't remember where I purchased them online but Newegg carries the exact package that I have.
Have a great day and go create great mail!
