My very first Swap and first ATC

Though I've done a few minis that you can view on You-Tube under TheKncLodge, I just joined my very first swap and this one is for an ATC, which I've never done either.  My assigned partner over at Swap-Bot has over 1000 swaps! I'm excited and a little nervous to get this right...
The swap is for an ATC with a puzzle piece in it.

I will update when I finish the ATC.
