A special touch to any garden, walkway, or path is to make a garden stepping stone with a personal touch. The nice thing about making your own stepping stones is you can press any items you want into concrete for interesting effects or leave plain. Gather a few supplies of decorative pieces you don't mind permanently setting outside, and invite a few friends or children over to help you create your stepping stones. Your finished product will be durable and long-lasting without costing you a fortune.
Follow the packaging of your concrete mix to prepare enough mix to fill your pans. Mix the concrete in a bucket or wheelbarrow, slowly adding your water so you don't end up with too runny of a mixture.
Coat your pans with a quick spray of non-stick cooking spray. Place any sprayed pans on some old plywood or on a spread-out trash bag.
Scoop the concrete mix into your pans, filling them all the way to the top. Give the pans a few taps to encourage caught air bubbles to rise out of the mix.
Level the concrete by running your board over the top of the pans. Let the concrete set up for 30 to 40 minutes.
Push your mirrors, marbles and tile pieces into the top layer of the concrete, so they are roughly level in the mix. Create any patterns you would like with your decorative pieces by using different colors to make shapes, letters or images of animals and insects.
Leave the stones undisturbed to set up and dry completely for about three days. Pop the stepping stones out of the pans on to your grass and let them sit for a week. After this full curing of the concrete, you'll be ready to set them up in your yard.
