I, Michele Grady, also have been thinking a little more about my idea for my charms... but thinking is all I could do this week. I have had family from out of town staying at my house all this week which has left no studio time to work on my prototypes. Hopefully next week I will have some time to work on them in between catching up on all the work I had to put off doing while my family is here! I am leaning towards using some photo etching in my charms. I am not sure of the exact design as of yet or what else I will incorporate into my charms besides the photo etching but I'm sure that will come to me soon enough. Here's a sample of some pieces of copper that I have photo etched in the past. Although you can't see the patterns very well on the dirty copper in the photos, the finished pieces are quite beautiful!
*CS7 update...Shannon Conrad of RubyGirl has received all the CS7 charms and they have been shipped back out to the charm swap participants. I was so excited to get mine in the mail last week! Here's a look at all the charms and who they were made by.
