Print your image: Start out by printing out a paw print image or any image of your choice to put on the front of the mason jar. if you choose to go with a paw print you can use our free printable should fit perfectly on the front of a 32 ounce mason jar.. Link is in the direction in above post.
Create your tape template: Place painters tape on a piece of parchment paper—you’ll want it to be big enough to place your paw print image on. You are essentially creating a custom sticker.
Secure the template: Place glue on the back of the printed image and stick it down onto the tape. Once you’re done, you’ll be able to peel off the parchment paper and have a ready-to-cut sticker.
Cut out the shape: Using scissors and/or an X-ACTO knife, carefully cut out the image on the tape.
Apply to the jar: Peel the parchment paper off the back of your homemade sticker and place it right on the jar where you want your design to appear.
Spray paint: Spray paint the jar and lid, allow to dry completely, and repeat if you need another coat.
Peel off the tape stencil: Once the paint is completely dry to the touch, use the tip of your X-ACTO knife or your fingernail to carefully lift an edge of the painter's tape. Slowly peel away each section of the paw print sticker to reveal the clear glass underneath. If the paint feels like it wants to lift with the tape, lightly score along the edge of the tape with the blade before peeling.
Add a clear coat: Spray over the mason jar and lid with a clear sealant, allow to dry completely, and repeat with a second clear coat. Let it dry completely before filling with treats!
