It is not that difficult to make fencing out of the pallets. All we needed was some pallets (looks better if all are the same size and shape), some wooden fencing posts (we have user reclaimed ones), some outdoor paint (optional, but looks much better if painted), some screws and fixings.
We have started with measuring and positioning all the elements to make sure it fitted the area. We have used some of the existing posts, but if you do not have one, make sure you dig the posts deep (adding some cement makes them more stable and last longer).
When all the elements ware measured and cut to required size we have painted everything white (the paint must be suitable for outdoor use).
With all the elements painted and dry the only last job was it to screw it all together. Job done.
