Porcelain Cups - I bought two mugs for $1.75 each at Walmart. You can probably find similar tea cups like the one in the movie at a Goodwill or another thrift store. Personally, I prefer to drink out of cups so that's why I chose those.
1. Step One: Make sure you wash your cups before you start marking on it. You don't want any sort of oils on them. Now, use your sharpie and slowly start making little dots to form the grim. I think it was best to look at a photo reference to follow by, so I provided one for you!
