Having a blue moment

First off, I love this rug from Dash and Albert.

Also, I'm still thinking about those cyanotypes...
I wonder how they made a sunprint of a building?

I guess one way to make that print would be to pick up some inexpensive glass negatives on eBay. This vintage plate of Venice is only $7.99 right now.

Reminds me of the orange architectural photographs that Matt from Top Design used in his LA loft.
