I have always loved the look of stippling but it drives me crazy to do. You have an amazing talent for it and more patience than I ever did! Looks absolutely beautiful. PS. Not sure if you knew but ATC have a thread in the paper craft section http://www.craftster.org/forum/index.php?board=259.0#axzz2pvbn9UyD Lots of beautiful and fun cards there too!
I never stress the time estimates. I do what I want and if it takes a little longer or goes quicker than I thought I am fine with it. As long as I am satisfied with the results and I had fun making it. Everyone works at different rates.
