I'm also looking for a subtle connection to real estate (house, key, mission bell, door, fountain, etc.) so that it's not just a pretty symbol. Thanks!
286 is really pretty, almost like a stained glass window, which I like very much! I'm not sure about the outer edge, though. I think I'd like a thicker border or something more defined. Something less delicate on the edges. Thanks!
These are both very pretty! I don't think they draw a connection to Spanish style, though. There are key shapes in Spanish design that clearly identify with that type of style. Quatrefoil is often used as a tile shape, for instance. I'm trying to think of others, but I don't know the names of the designs. Does that help at all?
Thank you for showing me that tile. It's beautiful! Although vary similar to what you have above, it's more varied in its pattern and shapes than yours, which I do prefer.
