I found a youtube video of someone making a rose from copper (sorry I didn't save the link) and made it from steel instead. For the petals I cut 3 3" discs from 20 gauge sheet, divided them into 5 sections each (cutting to within 1/4" from my center hole) and cut a small "V" notch between each petal. I then hammered them to give them texture and a more "organic" look. Then it was as simple as putting them together and bending the "petals" until it looked like a rose. I "cheated" and used a small torch to heat the petals so I could isolate the heat. (I could have bent them cold but I didn't want to take an unnecessary chance of the steel splitting). The stem was heated and textured, drawn down on the end to accomodate the petals, and then hammered flat (like a rivet) once the petals were on (of course, this done BEFORE the petals were shaped).
This was my first time and I thought it was a lot of fun...plus my mom and wife loved them!
