Applying BAMF Stickercals to your tumbler/surface is easy! Again, make sure that you have a clean smooth surface before applying the stickercal, otherwise it is as easy as applying a sticker. Stickercals can be difficult to maneuver, so ensure that where you want to stick it is where it is going because pulling it up and reapplying it can be difficult. I recommend watching Jessica Flynn’s YouTube review here, as she shows you how to apply the stickercals to ensure they are even and placed accurately. You can apply stickercals with or without transfer paper, but it truly is not needed. Using your finger or a squeegee, make sure all the air bubbles are out and the decal is completely stuck to the tumbler, rubbing from the center of the decal out. Ensure there are no fold or crinkles as this may show after epoxy. The clear outline of the decal may show depending on the style and color of the cup being placed on but is typically blended in with the cup after a layer of epoxy is applied on top. At times, after epoxy, the clear outline may still faintly be visible, and again, this will depend on the design/color of the cup. Typically, on lighter color and glitter tumblers the outline is rarely noticeable but may show faintly on dark solids color tumblers.
