Our machine has two sizes of buttons: 1 inch (25mm) and 2.25 inch (58mm). The top mechanism does have to be changed to switch between sizes. You must print your graphics to fit the desired size and cut them into the appropriate circle size. Be aware that the outer edges of your design will fold under to attach the button. You can use the Circut to design and cut your circles. Follow the Sticker-making directions, but cut out regular paper rather than sticker paper. For large projects, you will need to provide your supplies.
