Have you ever thought of making a carpet graphic of a large ruler? My thought is getting one made, putting it on my middle front compartment and then using that to measure fish instead of pulling out a ruler. One less thing in the boat I have to worry about. Just thought it may be a good idea. If you make millions off of it, I'd at least like a Christmas card. :)
In all seriousness, I would like to get that made up. If you think it's something you could do, PM me.
