Download the PDF file for the cupcake toppers. Open the file in a PDF reader such as Adobe Reader.
Print the cupcake topper. Make sure you remove printer margins in your printer settings before printing so the printout is sized correctly. This setting is labeled "Actual Size" in Adobe Reader. Other programs may call this setting "No Margins" or something similar.
Use scissors or a paper trimmer to cut the border around the cupcake toppers. Cut each column into a separate strip. This will allow your craft punch to reach the cupcake toppers. Use a 2 inch craft punch to cut out each cupcake topper. Position craft punch precisely to avoid white edges.
Put a small amount of glue on the end of a lollipop stick (1/2 inch or so). Attach topper to lollipop stick and place face down on a flat surface to dry. If you want two-sided toppers, repeat the same process for the other side of the stick once the first side dries.
