Please note, these are digitized embroidery designs and monogram fonts. They are not patches that you sew on. You must have an embroidery machine to work with these files and a way to transfer the files from your computer to your embroidery machine - (usb, memory card, box, etc.). With the monogram alphabets/fonts each letter is a separate design and you must layer or merge the designs together to create names or words.  If the software that you are working with does not allow you to edit, re-size, or merge designs together, you may need additional software to utilize these sets.
