Scratch-n-Sniff ATC

So I've noticed a lot of times when ATCs are colored theme, people use a collage of stickers and such to make the themed ATC. So, while I was at the store, I found a big variety of scratch-n-sniff stickers and thought that would be awesome to make an ATC about this! So, if you're one of those who don't believe in sticker ATCs, then please keep your comments to yourself and not spoil the fun :)

For these ATCs, they are any themed. If you can try to make it something you know your partner will like. Then, incorporate some scratch-n-sniff stickers into it! Make it look nice. Average 2.5x3.5 size please. If this isn't popular, I'll understand. Just thought it would be a cool idea.
