A pretty easy project really .All you need is your saw ,paper ,metal sheet ,patina , hole punch pliers ,chain and jump ring .
Draw your clover leaf onto paper and stick that on the metal sheet .When I make something simple like that I use 18 gauge sterling silver. 20 gauge is too thin in my opinion .I know a lot use 20 or 22 gauge as the cost is much lower. After transferring your design onto the sheet simply start cutting with the jewelry saw. File your edges . add patina ( for polishing you can use sand paper or steel wool )
punch a hole add your jump ring and voila . done. I added mine to the guitar i made the previous day,
if you are interested . I have a shop
