If your logo is fairly simple in design and you don't want it large in size, then embroidery may be a good choice. Also, it is more cost effective to embroider than silk screening if there are several colors, as it is easy to change threads versus making another screen per color. There is a digitizing fee to convert your file into a file that the embroidery machine can follow (essentially it must be redrawn with thread color and instructions). Embroidery is durable, but lines will not be as crisp and sharp as silk screening.
