I was wondering when some one would ask about the tape. Here is a tip for everyone. Its painters tape. We used it with these steps to hold in the poly sand on the edges of the steps and where 2 steps butted up against each other. As for the big holes the round pavers create, the pavers are supposed to be a "cobbled" look. I really like them, and talk about an easy paver to lay. But wowzers do they use A LOT of poly sand.
