The first thing I did was prepare my bottle caps. You can buy pre-flattened bottle caps for $3.59/dozen. These are also nice because they don't have any kind of liner in them that needs to be removed. Commercial bottling caps come with a liner to help seal the cap onto the bottle. The downside is the price and they don't already have a hole punched in them. I find it easier to punch the hole with my McGill 1/16" hole punch before the cap is flattened, so I started with these black bottle caps available for $2.99 for 50 or $4.49 for 180.
McGill 1/16" hole punch. If you punch in as far as you can the hole will naturally fall in a good place for hanging after the cap is flat. Note: If you are not going to flatten the cap you'll need to punch in just a little further for it to hang correctly and it's best to use a nail to hammer the hole with a piece of scrap wood behind the bottle cap.
If you're using a Sizzix or other machine and you make your sandwich too thick on top the cap edges will actually embed themselves into the plate, so make sure you use the white platform along with some combination of plates that is 3/16" thick on top. I use the Sizzix Big Shot Express but I use my Cuttlebug C Plate since the machine didn't come with a plate that thickness.
These little split rings are a little hard to pry open (like a key chain rings) but they are very secure. They won't pull apart like jump rings can. My trick is to poke an awl into them, carefully and angle it to hold it open while getting it started the hole. Sometimes I use needle nose pliers to circle it around. I guess some people do all this with their fingers. That's hard on the nails. There is such a thing as a specialized plier for opening split rings, but I found my dull awl worked ok.
Now they're just begging for decoration. I used 3 basic ways. For a simpler project, select just one.
Rubber Stamped Bottle Cap StickersI used a sheet of 1" circle stickers. These are available for $1.99 for 3 sheets which is 240 stickers. I cut two rows off of one sheet so I could keep the other part of the sheet for another project. I stamped a crackle background image onto the stickers and then pulled them off the sheet and laid them on my non-stick cutting mat. You can use freezer paper or extra sticker backing, too. I was using small stamps on this project but sometimes I like to use images that are larger than the 1" circle and I don't want the image to overlap.
1" epoxy dots over the stickers available for about $3 for a pack of 12. Just take care, if your image has a right side up, to keep in mind where the jump ring will go when you apply your sticker.
You could do the same for the backs, without or without the epoxy dots. If you don't use epoxy dots you may wish to seal the stickers with a clear glue like Glossy Accents or Diamond Glaze.
I wanted to do something different using the metal from a soda can.
Embossed Soda Can Shapes
I used a pair of dull Kai scissors I needed to get sharpened anyway. I wouldn't use the ones I cut rubber with because it will surely dull them. I poked hole near the top of the can with an awl and forced the tip of the scissors into the hole and cut the top off. Then I cut down the side and cut the bottom off. Wearing protective gloves is not a bad idea, to protect yourself from the edges.
Next simply cut shapes with paper punches or metal dies. I used both a spellbinders die and a paper punch. For die-cutting, I found I needed to shim my Cuttlebug with a piece of cardstock to get a little stronger cut into the metal. After I punch the shapes I added some texture with various embossing folders.
Vintaj Patina Inks and Adironack Alcohol Ink mixed with the Snowcap white color for a little extra opacity.
Vintaj Inks by applying two colors at a time to my felt applicator tool and just dabbed it several times over the leaves until they were covered and turned them over and did the same thing on the printed side of the metal.

the Ultimate Glue by Crafter's Pick, which dries clear so the stem wouldn't uncurl and fall off later.
