I searched for free images, alterred and edited them in GIMP (free image editing software) for high resolution. Printed the images to the PnP Blue using a laser printer (must have melted powder, inkjet doesn’t work). Cut the patterns and used a regular iron to transfer the patterns to the freshly sanded/washed surfaces. Used ferric acid purchased from Frys Electronics. I didn’t use any heat like the blog described, and within 2 hours had a pretty deep etch on the first few. As the ferric acid weakened the etching took longer, but they all turned out really well. I hope this is helpful to anyone that is interested in trying it out!
