I did manage to get bits and pieces done on the window+door prep over the holidays, despite travel and sickness and insane work schedules :

Now all the windows and door(ways) are assembled, painted, and sealed. I believe I'm finally ready to start assembling the house structure!

(That handle on the single door is a fixture that I found at Michael's or HL-- "Tim Holtz idea-logy" ring fastener. I thought that it looked like a nifty handle.)
