Junk Mail ATC challenge

How creative can you get with limited supplies?

The challenge for this swap is to create a collage on an ATC using a single piece of junk mail, no other embellishments added to it. An additional sturdy backing piece will likely be needed however.

Single piece of junk mail =
* one envelope with all its contents
* or one flyer
* or one ad (can be a single page ad or multi page ad, such as a local grocery weekly ad insert)

One 2.5 x 3.5 ATC
One swapping partner
Plastic sleeve not required
