I use LJ's brand of coated wire. The 15lb is quite pliable and easy to work with. The 25lb is a bit stiff to tie the knot, but wraps neatly when twisted.
I pull about 6-7" through the D-Ring, tie the loopy knot (can't for the life of me think of the correct term for this type of knot), then twist with fingers so each wrap is snugged up tight to the previous one.
Keep the knot part that is around the hanger loop loose so the knot can freely move.
Snip the end clean, so there isn't that nasty pokey little bit of wire extending out of the plastic covering.
Usually gets around 18-20 wraps. Maybe overkill? But what's the harm? I will do less on very small frames.
I'll go back and give the whole thing an additional twist with fingers or broad nose pliers to really snug it up.
I like Wally's idea of a shrink tube to really make it tidy.
In most cases, I don't think many customers care what the wire/hangers look like.
However, attention to little details like this could improve the impression of the quality of workmanship.
Hah! I just noticed this thread started about10 years ago!
I hope the OP found a solution.
