After a trip to The Wizarding World of Harry Potter last year, I got one of their plastic souvenir butterbeer mugs and was dissapointed by its distinctly non-magical and non-quality feel. I wanted to give my muggle guests a more authentic experience, so I made a set of etched butterbeer mugs for serving the legendary beverage. These mugs will also be "party favors" for each guest to take home with them, and I'm sending a few pairs of mugs to my more Potter-obsessed friends.
They are really inexpensive and easy to make, and using these techniques you can create incredibly cheap and detailed etchings of absolutely anything.
Step 1: Materials
Glass Mugs (I used these and they are the perfect size. They really feel substantial in your hand), washed and dried
Exacto Knife (use a new blade)
Butterbeer emblems (download below)
You can use the two Butterbeer emblems I made, or easily make your own. For my mugs each image had to be 3" wide. Print out your labels on normal printer paper. I will be switching between patterns in the instructions, but the process is exactly the same for both labels.
Step 2: Stencil Prep
lay a piece of masking tape on the parchment paper so that it covers the whole design. I used 2" thick masking tape, but if you have a smaller width you can simply overlap the edge of the tape to make a solid stencil. It will be a little bit more difficult to cut if you use thinner tape. Make sure to tear your piece of tape wider than the parchment paper to that it also touches the design paper, holding the whole thing together.
Put your little stencil rig on a lightbox or tape it to a window so you can see the design clearly through the tape.
Step 3: Cut the Stencil
I found that it was much easier to cut out all the little inside pieces and curves of each shape before cutting around the outside curves. i like to turn the paper a lot while cutting, so for me the light table is much easier to use than a window.
Step 4: Adhearing Stencil
Peel the two pieces of tape off of the parchment paper slowly. If little pieces of paper stick to your tape design, use tweezers or your knife to get them off.
Align your masking tape stencil on your glass and press it down with your fingers, then smooth over the whole design with something hard (like a sharpie). Keep in mind if your guest/gift-receiver is right-handed or left-handed and plan accordingly.
Very slowly, peel back the top layer of masking tape, making sure that no pieces are getting left behind. When you are done your mug should look like it has a single piece of masking tape on it with no little pieces missing.
Step 5: Peeling Away the Design
For tiny detailed areas where there is a small floating shape, it is helpful to hold the shape down against the glass with tweezers while pulling the rest away with your knife.
Step 6: Etch!!!
I highly suggest running a few tests on some old jars using the directions on your bottle of etching cream as a starting point.. The things to check out are thickness of application, direction of brush strokes, and time left on the surface. See what combination makes the most consistent and most crisp design with the etching cream you purchased.
Step 7: Wash Off, Peel Off, Drink Up!
You will need to repeat this process for each cup. It doesn't take too long--I got my time down to 15 minutes a mug not including etching time, but the first mug took about 30 min. as I was figuring out the process.
The cost per mug is probably around $2.50 if your mugs are $2. I checked my local Dollar Store for glass mugs, but they were all out. If your store has them that would be great!
A variety of Butterbeer recipes can be found all over the internet, but if you want an "authentic" taste like the butterbeer at The Wizarding World of Harry Potter, find a recipe with a cream-soda base for the drink and a butterscotch flavor to the foam.
These mugs are sure to impress all your Harry Potter guests, and make great "party favors." Have a magical time making them, and enjoy the final movie!
