This was actually my first project I did after joining Craftster back in January and I just now realized I never posted it
It's fairly large at about 68"x42"
I spent forever cutting the pages and marking on the wall to make sure everything was straight! I was very happy with how it turned out.
You can find the rasterbator so you can make your own here: http://homokaasu.org/rasterbator/
Just give it an image and it gives you a pdf (if I recall correctly) that you just print and you are ready to go!
Thanks for looking!
