I started from a sketch as usual and went to town. Making all the triangles was not as easy as you would have thought. I got some of the sizes wrong so just went with it. I added some Bo Bunny stamps for texture. The little tab on the side of the photo actually has hidden journaling.
here is the sketch I used. It was found (by someone else) at scrapfriends.com.au
I would love to see your layout with lots of triangles too.
