Cut vinyl with your Cricut machine into the shape desired. Use our guide for choosing the type of ornament as well as a design that will work well. Weed away all excess vinyl and add the vinyl to transfer tape. You can see the basics of working with vinyl here.
Use scissors to cut slits in your vinyl all the way around the outside. For something like this snowflake, make those slit go between each of the prongs. Do not cut the vinyl during this step. Then apply your vinyl to your ornament starting in the center and working your way out. Press down well and burnish. You can lift any areas that have wrinkles or bubbles and try to press down a second time. Then start lifting up the transfer tape leaving the vinyl on your ornament.
Once the transfer tape is removed, you can burnish the vinyl down well to complete your ornament.
