Pouring concrete and have a bit left over? Or do you have half a sack of concrete mix leftover that will probably go hard through humidity before you get around to using it?
Getting rid of this stuff can be a problem, so turn it into part of your landscaping.
Judy suggests simply taking a large bucket, or even just a ring, cut out of a bucket, and using it as a form for making stepping stones. You can even put decorative stones in the bottom and pour the concrete over them to end up with textured or decorated stones.
If you want to make letters out of the stones, make sure you write the letter backwards, because when you flip the molded paving stone over, the letter will reverse.
