I am signed up to Remodelaholic's email and I have just seen the most PracticalBeautiful idea from the States which I just had to post because it is just so lovely- Rain Chains!
Aged Square Cups Rain Chain, as the water just flows from one funnel to another.
Material: 100% Copper
Length of chain: 8.5' Cup dimensions: 4"H x 4.75"W
I'm not sure if they even ship to the UK and I doubt it will be a priority for many years to come but I just wanted to post it as I liked the idea so much. As and when I do put one in I think I would do it in the front corner of our house. I bet it makes a really pretty sound when it rains too.
