Th is size is popular because it is big enough that the words and images on the b utton can easily be seen and the parts are easy to handle when putting together. There is no price difference, but the quality of your buttons will be much better!Ģ-1/4' is one of the most common button sizes, often used for election campaigns, sharing photos with friends, hand drawn crafts at school, daycare centers, and summer camp activi ties. Note: It is important to order your supplies from this page and not the regular 2-1/4' parts page, because the T150 requires a slightly different sized mylar (2-41/64'). Then we'll send you everything you need to make them! :) Use the drop down menus to choose the product type and pack size (quantity) you want.
