Form for putting down paver stones?

I have a unique situation for an area where I want to put paver stones. The patio is at the bottom of some stairs, and in order to get the patio at the correct height, the soil will have to be brought up around 3 - 4 inches.

I'd like to wait and put down the soil in the fall when I can plant grass to keep it in place. Is there any way to build a temporary form around the patio area that will hold in the base material, sand, and stones that can be removed after I put down the soil? It seems like pulling out a form would make the base area (esp. sand) fall out when removed, but I wanted to see if there were any suggestions.

Thanks.

 

You will need to put some type of edging around your pavers to hold them in place anyway. I've seen plastic versions and I think they have metal ones as well. I've also seen mortar pilled up on the side. Your sand shouldn't be too thick. About an inch or so. Refer to the manufacturer's instructions. You should also see if they require a base material underneath the sand. If you are that concerned about erosion of the soil you build up, you should plant the grass right away. Just keep up with the watering. Sounds like it is a small area and shouldn't require too much water.
