Ideal Mosaic Mystery Cache

Janet and I have been doing some work around the house. We have different views on what we need.

Take bathroom wall tiles for example. I think lots of things could be okay. But she wants to find the ideal mosaic.

This is the front runner so far. Actually I quite like it.

Then recently I received this message. I thought it might be from Janet with more tiling ideas, but now I'm not sure.

“I have left a message waiting for you. It may help you if first you 'find perfect peace of mind'”

I asked Janet about the message but she just smiled and said "You reckon you're good at puzzles. Maybe it is not what you think? But I am sure you will find it."

But so far there is no perfect peace of mind for me.

Maybe you can help?
