A while ago we started edging some of our garden beds using rocks that we'd gathered for free. It's still a work in progress - some of the results can be seen here.
Here's our latest haul of rocks which we scored for free via gumtree. We got them locally from someone who just wanted to be rid of them - a good example of reuse and recycling in action, wouldn't you agree?
Incorporating this lot into the garden is going to keep us busy for awhile.
