Andy this isn't a direct line to the GW programme as such-perhaps if you could be more specific- because- and I may be alone in this- I do not understand what it is you are after-when was the programme on and what do you mean by "market a picket fence"
If you make it clearer someone might be able to point you in the right direction
I have read your post again and is it you want to make a fence out of a pallet?
Just google pallet suppliers if that is the case-you should find them in you area.
Just ask around. Building sites are a useful place to find discarded pallets. I don't know what you mean by 'pallet tops' as to make a fence all you need to do is use a crowbar and seperate the slats. I have a dozen double-size pallets on my drive and these were once used to tranport plasterboard. Wickes? Initiative?
My company website has a how to guide for building picket fencing if anyone's interested. As I'm new to the forum, I don't want to seem spammy. So if anyone's interested, please let me know and I'll post it.
