DIY tile transfer, or "how to make your oven stinky"

I came across a DIY tile transfer project via One Pretty Thing that I wanted to try, but I lacked the motivation for getting into the car to drive to the home improvement store to buy a single tile for 50-cents.  Instead, I had some slate kicking around that I figured would be neat to try a black-on-gray transfer.  The results: a rough start, but a better than expected final product. Here's how it all rolled out:

I followed the directions from the online tutorial which called for ModPodge on the front of the medium and then again on the laser print-out.  You then sandwich the two items together, bake it in the oven and then delicately rub off the paper with water until the image appears.

I wont lie: my oven stunk after baking the slate.  This is probably because I used outdoor-grade MP instead of regular, so lesson learned.  I also mistakenly trimmed the image when I should have let it cover the entire slate.

Disliking the initial results, I flipped to the reverse side of the slate, started over and covered the entire area with the paper. 

The results were a million times better and I liked the oxidized/grainy look.  This probably and shouldn't be the case if you used a light colored tile for your transfer, but I'm digging this vintage appeal.

Now onto de-stinking my oven.
