Here's a report of my own tying performed back in December. I had already torn and snipped my frenulum a little many years ago so it wasn't too restrictive to begin with.
I took an ordinary sewing needle and a piece of 0.5mm stretch magic.
So i cleaned the thread and the needle thoroughly (sharpened it too), used a clothes peg and a lamp to clamp my frenulum in a convenient position and provide a back light so i could see through the construction of the semi-transparent skin and find the ideal placement for the stitch. I aimed for a very shallow position (best to tie off a little at a time) and also tried to place the stitch as close to the glans as possible as this would be the part that was providing the most anchorage between glans and foreskin. I stuck the needle in with a slight twisting motion to help pierce the frenulum. It took a lot of force to get the needle through (skin is strong!) and it hurt quite a bit when i got it through, not more than an unpleasant sting though. I pulled the filament through then tightened a few very tight knots on top of one another. There was a painful throb each time my pulse tried to force blood through this newly constricted capillary. This was the worst pain of the whole experience but still it was not unbearable, maybe a 6/10 (I've had bowel movements that have hurt worse).
I treated the area before hand with a little germolene. This is an antiseptic with a little anaesthetic in it. It didn't seem to numb me much, maybe it made a little difference. I applied this consistently over the next week to keep the area sterile. In hindsight this may not have been a sensible idea. Apparently antiseptics can hinder the growth of new skin which is not really what you want when you are severing skin. Just keeping clean is probably enough to avoid an infection once the stitch is in.
I soaked the area twice a day for about 15 mins in a cup of warm water.
Eventually the stitch cut through after 10 or 11 days. When i placed the stitch I accidentally placed it a little deeper than I really wanted to (it's hard to get it exactly where you want) so I suspect it took longer because my stitch was a little deeper than most and so there was more skin that needed to be cut through.
All in all it was a positive experience. I have a little more freedom of movement in my foreskin, it doesn't roll over the glans so much and I personally think the frenulum free cock looks a bit better than one with an intact frenulum. IMO the frenulum is one of the most unnecessary, unattractive, inconvenient, badly designed parts of our anatomy and anyone who wants to do away with theirs probably won't be disappointed with the results.
Below is a before and after comparison.

In both pics I am pulling my shaft skin down to illustrate the degree to which the frenulum is distorting the shape of the head. The head is tilted forward much more before and hardly at all after. It also seems as if there is a large area of newly exposed tissue now that the webbing is out of the way. There's a tight, white strip of frenulum that is still restricting my foreskin very slightly. I might be tempted to do one more tie to rid myself of it but now I'm thinking I might just get the whole frenulum surgically removed anyway. I'm getting circumcised in 2 weeks time (mainly out of personal, aesthetic preference) and will probably ask my surgeon to remove the frenulum (I just think it looks better without). My frenulum is a fairly insensitive, long strip of scar tissue by this point, no more sensitive than the surrounding shaft skin, so I don't think I'll be missing out on any sensation.
Anyway, thanks for all the helpful information guys. I've enjoyed having my liberated frenulum these past several months, even if it has only been a temporary change.
