I can't remember the last time I noticed the inside of an envelope. In fact, I can't remember anytime I've ever noticed the inside of an envelope. What's there to notice? In the super beautiful envelopes below- the answer is 'lots'. I came across this tutorial the other day and realized how undervalued this little piece of real estate is. Since my perfect brother got me a letterpress kit for my birthday, I'm preparing to send out quite a bit of correspondence. If all goes as planned, I'll be customizing the mess out of my envelope liners. Any suggestions for what might look pretty?
