Sandra, I really like your mandala's but wouldn't know where to hang one!
This is the exclamation I received last night at the local weekly knit and natter I go to. And you know what, I've had the same issue myself. I always do with art work, I fall in love with a piece but I can't visualise how it will look in situ so I don't buy.
Firstly, with the mandala's, they are small! ranging from 7 inch to 12 inch across, so they aren't major art pieces. But they are very versatile, most of them look equally pleasing on the reverse side and most look amazing in windows. You don't need to hang them either, they will stand propped up on a mantlepiece for example or blue tacked on to cupboards. So use these properties to your advantage, even to the point of being able to move them around your house and even move them outside in the summer months.
Below you can see how I have hung my mandala in the feature window, which brings even more attention to it's beauty. The other mandala has been placed in a small patterned glass window..
