LOTS of great information and techniques in Creative Chemistry 103 and I would totally recommend the class.
For this tag I've had a little play with the Distress Highlight Stamping Technique and I've used Tim's doily stamps for the technique. There is also some stenciling on here (little dots), wildflower die cuts from black cardstock, Idea-ology chit chat stickers and paper string, inking around the edges, black soot Distress marker for the marks at the bottom of the tag and to finish it off a light spritz of the Tarnished Brass Mica Spray from a good distance. I LOVE how this has made it look like the tag has little flecks of gold all over it!!! Hopefully you can see a bit of that in the next two pictures.
