Designing your own garden stepping stone is creative, fun and economical. Supplies are easy to get and use and the outcome is quite impressive. If you have the opportunity for children to help with this, they will really enjoy themselves. Garden stepping stones will add a unique touch to your garden and serve as practical steps to keep your feet clean and dry.
Decide what kind of plastic mould you want to use. A simple and inexpensive idea is to go to your garden centre and pick up a few of their clear plastic drainage containers they sell to put under plant pots. They are flimsy but are suitable for this project. Get creative and use whatever mould you would like as long as it can hold about 7.5 cm (3 inches) of Quikrete.
Place your decorations on the bottom of the mould. Any variation that you like will work. Most department stores have an arts section where you can find glass marbles, decorative stones or broken tiles to use in your stepping stones. If you are concerned about the stones moving when you pour the concrete over them, use a bit of double-sided tape to hold them down.
Mix your Quikrete according to the directions on the package. It is convenient to work in a wheelbarrow and stir well, adding water slowly until you have a pudding-like consistency. The mixture gets heavy and the extra leverage of the hoe makes it easier to stir all the way down to the bottom of the mix.
Pour the Quikrete into the moulds, being careful not to dislodge your decorations. Leave the newly-made stepping stones on a flat surface and allow to dry overnight. They should be much lighter the next day and be hard. They are still fragile at this point, so handle them gingerly and do not walk on them.
Turn the moulds over and remove the stepping stones from the mould. Remove any double-sided tape if used. Your decorations should show up nicely and, if any Quikrete has covered them slightly, they can be brushed clean. Place them in your garden and allow to cure for a few days before walking on them.
Seal the Quikrete by applying the concrete sealant to the decorated side of the stepping stone. This will help it to weather longer without taking on stains from leaves and mud.
