See our 'posh' brolly! It doesn't have a base and is merely stuck in the ground. It's there to give the dogs some shade because our garden faces south and is a fantastic sun trap. Mind you, they lie everywhere but under the brolly and we end up having to take them, puffing and panting, indoors...... and the dogs fairly puff and pant too!
The patio is full of cracks and looks like it's ready to fall apart quite soon! But if we replace it, we'll disturb all the mice, frogs and toads that live under it. Still, the house is almost 120 years old and that old stone has never been replaced so it can bide a bit longer. :D
