You'll need adhesives to assemble certain printables, like attaching cupcake toppers to paper straws. A printable designer's go-to adhesive is usually a hot glue gun. They're inexpensive, and the glue is guaranteed to keep everything in place. You can also use glue dots, double sided tape (permanent is preferred), glue sticks, or regular tape.
There are so many options for cutting out your printable designs. You can use a paper trimmer for straight lines and scissors for more intricate objects. If you plan on creating party printables, get a 2” round hole punch for cupcake toppers and gift tags. It's a minimal investment that will save you hours of time, and your hands will thank you. Also, check out the hole punch aisle at your local craft store for more options.
