Thank goodness for holiday weekends! I had time to finish the cuff and leaf it. It was a messy job and my backyard picnic table is covered in copper leaf, but I think it will turn out ok. After covering it in the leaf, I let it dry and then rub it all over to take off the loose leaf. You can see in a comparison how the copper oxidizes. The swatch is beginning to turn brown.
I want to be able to make it reversible so I think I will sew buttons on both sides. Also, that will make it so it can be buttoned like a cuff with cufflinks. It gives the piece a lot of options for fastening. I ordered some copper buttons from Etsy so I am waiting for them to show up before I finish it.
