I went to the ABANA website and found the "26 skills required for a journeyman smith" and I work on one of the new ones when I get a chance.
I am nearly finished with a fireplace screen that is made of "S" and "C" hooks, forged rings, spirals, etc. Just stuff that I cut up, pounded out and filled the required space. It started to look a little like a sunflower so I pounded out some good sized leaves to stick in there, too.
that's not to say I don't have "smith's block" but the above advice about an iforgeiron project, or an anvilefire demo, is a good route to take. There's usually at least a couple different skills involved in each project and you'll probably want/need to do them a couple times each.
It gets a little annoying at times, but soliciting ideas from family and friends puts you in the shop working metal and they have a pretty, hand-made gift in exchange for a good idea. Then they won't leave you alone... it's kind of a catch-22
Good luck!!
