Paris in B & W

Greta is hosting this swap - we had to use Collections tiles, and our theme was B&W Paris. Here are my offerings:

I had all sorts of technical difficulties with this swap. I've discovered that my stupid printer won't print in black and white if the colour cartidge is empty. What the......? I thought I'd go to my sister's house, and her printer (considerably newer than mine) behaves the same way! Is this a printer virus? Anyway, and expensive trip to Officeworks later, and these tiles are done. Talk about suffering for art!
