This is what i did
Go out and cut some nice long straight hazel branches, Put them in the loft/on the radiator and leave them for 3 weeks. Then cut them into 3Ft lengths and then put a point on one end and trim the bark off of the other and then have a go at straightening any small bends in them,i use a electric hob and this works great for me, but some people wrap the bends in a small cloth and put hot water over it, iv not tried this but im sure it will work,
Heres a few pics for you mate
The tops
And the bottoms
