Sliding Surprise ATC

READ COMPLETE TEXT BELOW (in Comments):

I saw this idea in a card making book and thought it would make a cool ATC, too. For this swap you will make both an ATC and an envelope with a window for that ATC. When you slide the ATC out of the envelope you reveal a surprise in the window. The sample above has a quote on the inside of the windowed envelope.
You might want to make an ATC with a quote on it that reveals a picture on the inside - or you could have 2 related pictures (before & after?) or 2 parts of a quote on the ATC and inside the envelope.
I have created a pattern for the windowed envelope (actually you can get 2 on an 8x11 page) at the web address below - or email me and I will send it to you.
Senders choice of theme, but make it something you would like to get yourself.

Standard size ATC 2.5 x 3.5.

1 ATC for 1 partner.
