Very large canvas sheets that can be rolled up and easily transported.

Event sponsers logos are laser cut out of the fabric, with the large spaces done in a fine strip pattern to maintain the structural integrity of the stencil.

Several months before a sporting event, the stencil is rolled out across the fairway, or the in goals / end zone / outfield and flower seeds and fertiliser is scattered onto the stencil.

By the time your event rolls around, the sponsors' logos are a blaze of natural colour.

Smaller scale domestic version also available with messages such as "Please pick up after your Pooch"

You could do this with fertilizer too.

Why not make a rather heavy mat, place it down on your lawn and cut the grass that's still sticking up. Give it a day, the other grass will rise back up, and half the grass is 3 inches lower no questions asked.

I had that same halfbaked idea a while back, [iamnafets], but discovered it was baked.

Why was this idea not brought to my attention sooner?

In fact, just leaving the stencil in place for a few days would etiolate the covered grass, leaving the sponsor's message standing out in a deeper green.

Works well until that awkward moment when the sponsor mergers or goes bankrupt. Eek, like trying to overdraw an old tattoo.

This would be very good for making crop circles.

You could do color logos by using dandelion seeds, clover seeds, etc. in the stencil holes.
