Abstract Thursday

Thanks to all the reminders from blipmates I was up bright and early this morning to take my car to the garage for two new tyres.

On my way to the Three Sisters Bake for a coffee to while away the half hour the garage needed, I passed an old cottage with a moss- and lichen-covered slate roof and decided the pattern of the slates would do for this week's challenge. I may have accidentally done some faffing on picasa...

Dreich!
