Collage in light card. Numerals cut freehand. I was mulling this over in my head, among other ideas, but I didn't get around to actually creating it until about 9.30pm, just before the start of Week 12. Perhaps I should have played a little more with the negative shapes before gluing down, but I wasn't sure if I was going to do any overlapping. It ended up fairly random.
Update: I decided to have another go at numbers, using the previous week's architecture pic.
