I use Sure Cuts A Lot with my Silhouette Cameo. I have owned this software for seven years or so and have upgraded with each iteration. It is a versatile tool that allows me to format and cut many different kinds of patterns, signs, slogans, etc. It is especially useful for cutting stencils. Why pay to buy stencils when you can cut what you want in the size you want for your particular usage? Forget about Cricut—go Silhouette and Sure Cuts A Lot if you are interesting in cutting plastic, vinyl, paper, and other media for crafting!
