to tie an hair rig is easy. also practise with some mono till you get it perfect.
1. tie a small loop in one end of your desired hooklength
2. pass your hooklink through the BACK of the eye on your hook
3. wrap your hooklink around the shank of your hook, roughly 5-6 turns is good.
4. pass the hooklink back through the eye on your hook, through the back again ( i may be wrong about passing it through the back rather then the front on step 4 )
your hook should now be held on your hooklink, with what is called a knotless knot which u have just tied.
5. attach your swivel to the opposite end, with a grinner knot, or you could use a double hand loop knot.
for these knots look at this months carp.com magazine brian atkins has wrote an article with the grinner knot, and double overhand loop knot in. it even shows u a step by step instructions.
hope this helps.....
