I took an online soldering class from Sally Jean Alexander months ago and learned to create 3 dimensional boxes. The soldering is easy compared to finding things to put in the boxes.
Soldering allows you to collage, incorporate fabric, found objects and add lots of bling. When finished you have art that you can wear. Doesn't get much better than that.I do recomment Sally as a teacher and she has some great online classes. I do caution you that if you have a problem she will not attempt to resolve it - so beware!!
