Things are looking up in today’s jigsaw puzzle, if you’ll pardon the pun.
I visited a few cathedrals over the years in my travels. I always found it fascinating how they built the ceilings and support columns without modern methods.
The brickwork in some of them looked amazingly difficult, even by today’s standards.
All the angles and curves make today’s jigsaw puzzle a unique challenge.
Enjoy!
