Last time I bought a commercial mesh fencing was about 8 or 10 years ago. It's Scale Scenics[ div. of Circuitron] Brass Micro Mesh #652-3501...if still available. Expensive though, it was around 6 bucks Canadian back then for 2 strips about 2" by 6". Made a very realistic fence in H0...probably 'fine enough' for N as well. I tinned it, and soldered it to pre-tinned 1/16 brass tube for posts. Trick is very much the 'thinnest' paint job possible...and use a flat gray...I brush painted it, and used a hair dryer to keep the openings open.. regards / Mike The tips, modeling, and pictures on this thread are very good.
