Please choose the correct ending to complete the given sentence: Home and Garden: [header] How to decorate garden stones [title] Choose smooth stones. [step] Virtually any type of stone will work well for this project, so focus more on its condition, rather than what type it is. Favor those with smooth, rounded surfaces.

Ending1: [title] Pick stones that are the same diameter (often 14 to 24 ") and the same length. [step] A fine, round stone is better for shading, whereas a finer, more decorative one is better for shading. Ending2: Avoid chipped, broken, or jagged ones. [substeps] Don't limit yourself to stones with " perfect " shapes, like exact circles. Ending3: [substeps] Round stones with tiny fractures, such as a stone whose parts are curved will work better when it has larger or larger beads on its surface. Rounder stones are easier to work with, with smooth surfaces with rock structures sculpted along the rim. Ending4: [substeps] Avoid smooth, uneven stones like marble or sandstone. Check for fine stone that has traces of dirt or grit across the surface to avoid looking too rough.
