All the cutting files offered here can be used for personal and commercial use. Many of these sets are my exclusives which mean they are not offered anywhere else. These collections includes the following formats: SVG, AI, DXF, EPS, PDF, GSD, WPC, MTC, JPG, and PNG. These cutting files can be used in their original format, or converted into formats compatible with die cutting machines such as: Black Cat, Cuttlebug, Craft ROBO, Pazzles, Wishblade, Sizzix, Gazelle, Silhouette, Klic-N-Kut, and others. Please Note: It is no longer possible to use anything but Cricut's own files with their machines. Please be sure that the cutting file formats being sold here are compatible with your specific software program and/or cutting machine. You will receive several cutting file formats (SVG, AI, EPS, GSD, MTC WPC, and DXF) which will allow you to create a finished product using a die cutting machine, in conjunction with a software program that supports cutting files, such as SCAL (Sure Cuts A Lot) or MTC (Make The Cut.) You will also receive paper piecing patterns in JPG, PNG, and PDF file formats, if you prefer to print and cut the craft project by hand, in lieu of using a die cutting machine. These sets includes a “finished example,” in JPG and PNG, to aid in placement of the various pieces. This “finished example” image can also be used as a graphic / clip art image for craft projects, scrapbooking, web use, etc.
