TechShop San Jose's vinyl cutter and media blaster made this gift possible.
Step 1: Make a stencil using the vinyl cutter
Step 2: Weed the vinyl and apply transfer paper
The transfer paper helps to hold everything in place while you position it. I made a horizontal line above the letters to help align it on the flask.
Step 3: Apply the vinyl sticker
Step 4: Sandblast the flask
The media blaster doesn't photograph well, so all I have is an "after" photo.
