If you're a fan of the Arts & Crafts architectural style (Mission, Greene & Greene, etc.) then you almost certainly appreciate the aesthetic of the hand-crafted tiles from Motawi. Unfortunately for my budget, each of the tiles costs about $50 (at the low end). We've purchased a few of them and loved them -- but I must control myself.
I've been buying the calendars of Motawi tiles on-and-off for several years now, and I've never been disappointed. Each month has a well-photographed picture of a tile in their current catalog (I don't think there are any repeats from previous years) so my kitchen will be joyously decorated all year long. It's also a good calendar (in regard to completeness of dates and such).
