The ping-pong net is perfect, since it's a ping-pong table. I wanted to use those for folding tables, but the plastic puffy tables just crush under the clamp.

So, I did the gutter guard fences.

I used plastic flexible corner bead (for when you put up drywall and spackle the outside edge of a wall) and used little zip-ties to hold the gutter guard to the corner bead. Since they were temporary tracks, I simply duct taped the fence to the tablecloth that I covered the tables with (very large one bought for cheap on ebay). The only problem is the gutter guard likes to try to curl up. It worked great for the school fetes I did. Here's a picture of the last one I did:

Thanks for keeping a few R1 in there, just for me.

Looks like a great layout, and you even got a 4 lane section in there! Wow.

I echo UshCha, and suggest ebay for some cheap nets and clamps. The clamps I got for testing were quite adjustable and could be made to hold the next just about anywhere. One set for the ends, and an extra set to make corners in the net. Get as many as you need to surround the table, and probably still only cost $30 or so.
