I found all of the following projects on Pinterest. All links go back to the original blog there the Pinterest post came from, and all photos belong to the original blog posters.
A blog named Mamie Jane's featured several trash to treasure projects with old casters. I love the book ends and the photo wheel.
Who would have thought of building a snowman from old propane tanks? I like this one featured on Pieced Pastimes.
I love the pot rack that Mia from Lilly and Mia's blog created from an old cast iron fence.
A blog called Totally Green Crafts featured wine bottle lights that are cool!
