How To Build a Stone Planter

Cleave an end from four blocks and position them at the corners of your rough outline. Place blocks of varying sizes between them, keeping the sides parallel. Divide the interior area with two walls that create equal-size planters; every other course will overlap the main walls, so just make sure you won't be left with gaps between blocks. If so, you'll need to adjust your planter's width. Once the layout is complete, mark the outline with a spade.
