I recently started making these little roses and wanted to share how I do it. I use reclaimed copper gutter for these. I use this template. I tried to find the original designer of this and could not, so if you know who it is, feel free to share! This is a great pattern. Print it out to whatever size you want. I've tried it in several different sizes.
I use rubber cement and glue my paper pattern on to the 24 gauge copper.
I cut it out using a jewelers saw.
Once it is cut out. I use my cross peen hammer and hammer the outside edges of each of the petals. I anneal it with my Mapp Gas torch to soften the metal and to make it easier to work with. I then roll it up and using round nose pliers I fold the petal edges over however looks the best. The video below shows these steps.
After I have it shaped the way I desire I soak it in vinegar to clean it up. I use a wire brush to scrub it and to make it shine. I patina it with Liver of Sulfur. This is the final result once it is all finished. I cut out a round area with two leaves to hide the base of the rose. I use E6000 glue to put the two together. I love the end result. If you have any questions please feel free to ask. I gladly share knowledge when I can.
