I've done digital DD for the last 6 years... I am a bit behind, I haven't finished 2012 or 2013... but 2014 is done.
2012 became huge - I did a page per topic we did... that is why I'm still plugging away, but hey, great way to use new Christmas kits!
2013 - I got overwhelmed trying to merge 4 kits and reworking templates... than last year I kept it easy, one kit and one template set...
I'll be doing it again this year... its one of my favorite projects.
