Hi there Gary + Kg2v (welcome to the Guild

)
I've been away, but as regards Turks' Heads, this is the mnemonic I use for the way I tie them in hand:
On hand, number fingers thumb=1-little=5. Lay cord from centre of wrist to lay between 2 and 3. All loops are made clockwise on the left hand. I've never tried reversing them on the right hand, but it should work. Just a number means that you loop the finger indicated. The Overs and Unders run fairly close to the insides of the knuckles, not directly across the palm.
TH5Bx'n'L:
3; 1; 4; O-U-O; 2; U-O-U-O; 5 = x2+
TH4Bx'n'L:
O3;O2;U1;D2, O-U-O-U, 4 = x2+
I got this method because of two circumstances:
I'd seen a method of illustrating tying Chinese Knots using a hand cut out of cardboard. I think it was on
http://chineseknotting.org/button/howto1/ which is one of KnotMe's sites - the images have been updated now using a jointed wooden mannequin hand. Anyway, not long after that I saw an ordinary 5-bight TH in one of Geoffrey Budworth's photo-illustrated books, and the thought occurred to me that if I reproduced the flat loops on my fingers, I'd find it easier to tie. So I did.
I've never done any photos of it, and I'm having problems uploading photos to my Flickr site at present, but I'll post if I get them done before the end of August

Regards,
Glenys
