All of our designs are Machine Embroidery Designs. You will need an embroidery machine to stitch these designs. You will also need software/hardware to transfer our designs to your embroidery machine. If your machine does not allow you to combine designs, you will probably need software to combine designs [like SewWhat Pro or Embird] as well. It is the buyer's responsibility to know the format needed and if you have the appropriate software/hardware necessary to use the designs. We do offer full support and will answer any questions, so just e-mail us if you need something. We are not responsible for the quality of designs that you modify (including resizing). If you have problems with the original designs we will assist you in solving the problem.
