I would like to recommend this product for its low cost but great versatility

I wanted to share this brilliant find with you all. Last year, after some research, I bought some green debris scaffold netting from Ebay. For less than £25 i received a roll 2m x 50m. At first I was a bit sceptical, but a year on, I am absolutely sold on this product, let me explain. We had planted a willow hedge along the boundary with the adjoining farmers field and his Welsh Mountain Sheep enjoyed sticking their heads through the pig wire fence and munching on the willow shoots. I invested in a roll of chicken wire 3 feet high and attached this to the wire fence. This stopped the lambs, but the ewes just stood on the top wire and kept munching. So, I bought 8ft round wooden fence posts and drove these in 12 inches and to these I stapled the green netting. This has both made for an effective windbreak and has put an end to all munching of the new shoots. I thought this might last a few months, but for £25 was cheap enough to buy another roll. Imagine my surprise 18 months along and with a winter of fierce winds behind us, the material is just as good as when I fitted it. I used my Bosch PTK3.6 cordless tacker with 8/mm staples to attach the fabric. 
This year with the new 4ft wide raised beds built I used a length of this material on top of blue one inch irrigation pipe hoops to act as a white butterfly net over the brussels sprouts and cabbages. It has worked brilliantly. My plants are tall and healthy, so no shortage of light and no caterpillar damage whatsoever!
I see it has gone up a few pence since I bought it, but still a bargain and you can find it on Ebay at https://www.ebay.co.uk/itm/Debris-Scaffold-Garden-Netting-Green-2M-X-50M-Crop-Allotment-Shade-Windbreak/272622199722?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649

It's great stuff to speed up grass seed germination too

I bought similar from amazon, made a frame for brassicas, no cabbage whites got through so no chewed veg.

Here are photos of the brassicas bed and of the hedge

It’s good but make sure it doesn’t touch the greens or she will land on top and lay through it. 

Capelglyn

Not a problem. The hoops adjust so as they grow I raise them up giving a six inch margin between the top of the plants and the netting. The Brussels are now huge but still no caterpillar damage.

Is that water pipe from builders merchants? 

Capelglyn

Yes. 25mm blue alkathene water pipe. Next year I hope to make a free standing hooped frame which will fit all my beds and just move it around from one to the other as the brassicas rotate. I have tried various methods over the years. Netlon on canes with plant pots on top, like the ones Monty uses and other nets too, but I think this net and pipe frame works the best. I am so impressed with this material, that is why I wanted to share. Most of these things cost a lot of money and can be disappointing, but this is cheap and works brilliantly.

I think that’s the best method, you’ve done a good job there,

There is still some of that green netting 'alive' and kicking in our inherited mature beech hedge. I imagine it was used for wind protection when the hedge was first planted by the previous house owners. That would have been in 1994. Certainly lasts well...😁

It's been widely used for years as a windbreak, in the way @Topbird describes.
Vital in the north, and anywhere that's exposed, so that shelter belt hedging can get a chance of growing, and therefore protect anything else growing inside a hedge. 

Lyn's right - you have a very nice set up there for your veg
