I started off with the idea of having a red block patio, but early on my best critic advised me that he thought it would be cool if I used some of the blocks from the clothesline pad to make the patio look like a quilt block.
The blocks are not "grouted" at this point. I needed to get them all in place and be sure that I wouldn't need to move any more than I already had. When I was ready, I used a material called Poly Sand... I have heard it was advertised on TV, but I came by the idea of using it by word of mouth from a friend. The Poly Sand pretty much seals the cracks so weeds can't grow up in between. So far I'm thinking that was a very good choice.
I will post again soon.
