to draw the pattern head over to a craft store and grab yourself some fabric markers
Estimate how big you want the patch and cut a piece of scrap fabric that is that size
When using the markers, be sure to keep the fabric flat! wrinkles can be a pain in the butt!
Be sure to follow the directions on how to set the markers. Mine said either to iron the image or throw it in the dryer and viola! a new awesome patch to use!
