I have loads of broken branches in my yard, especially after the strong winds we've had lately.
For more broken photohunters, please visit the home of the hunt where participants post starting Saturday.
Sometimes broken branches are incorporated into my garden.
I also incorporate broken shells into my garden which I bring home from trips to the beach.
I have lots of broken tiles and granite which were left over from building projects which I use for edging in my garden. A friend told me about a pile of materials like the ones below that I could take and I loaded up my car with them years ago.
