I was in Switzerland a few years ago, and took loads and loads of pictures of architectural things. Doors, windows, fences,winding staircases, a sea of roof tops, lots and lots of geometric, and in my mind, artistic shots. Then, near the end of my visit, my memory card got full (yes, I've learned my lesson), and in order to take other needed pictures, I had to delete all the artsy-fartsy pictures. So, I'll just have to try to juggle my memory. ( or go back to Switzerland..)
Or I could just do a gingerbread house and use lots of large white rick-rack.
BTW I have a funny story of an engineer (my son) and an artist/chef (my soon-to-be DIL) making a gingerbread house when they were just getting to know one another. There was a protractor vs a spatula mini-war! Then are now still married since 10 years.
