I have had the Winter Berry cutter for a few years. It came with a set I had purchased. I needed leaves for a baby shower and figured I'd use the cutter. I purchased the PNG and converted it to a jpeg. Sent it to my Bib Blue printer and printed the image (actually the outlines) right on my cookie, then filled it in with Royal Icing. Simple. I love getting the images for the cutters. Makes it so easy with a printer. I just wish they were available in jpeg so I didn't have the extra step of converting the file. Not all food safe printers use png.
