I love Nikki McClure's work, so I've had a hard time getting rid of this beautiful calendar . . . from 2008. This week, cleaning out the back room, I found it again and decided to use it to make recycled mailers. Here's how:

Fold up a thin strip on the bottom, and a wider strip on the top.
Trim excess from flaps. Use double-sided tape to seal.
