Can you guess what I'm doing?

I've been a bit busy.  Can you guess what I'm doing?

I'll give you a few hints:

I guess it's never too late to finish something off your to do list for the year even if you are coming down to the last day of the year.  Better late than never, right?  I'll promise I'll show pics when I'm done.  Hopefully I can finish before the new year rings in.
