The discussion about hot cutting has been most valuable.
The diversity of opinions shows that there is no "best"
way to do it. 

One of the finest ideas, was the use of magnets to keep
rip stop in place. I have been cutting in kitchen on a
glass I put over the (cold) cooking plates - there is 
good, "air conditioned" ventilation. The glass is 5 mm
thick but I'll try magnets, there is a lot of iron under
the glass.

My contribution to the tips is... (this is very difficult:
my engineering english is limited on computing and I am
not a poet either).. a kind of leg to the soldering iron.
I would have called it a "standoff" if that would not have
already another meaning in kite vocabulary. 

The advantages of hot_knife_leg is:

- templates won't burn, because the hot tip does not touch it.
- with a finished sized templates the leg gives adjustable
  extra cloth for seams.
- with metall rulers the tip does not cool.

I made my hot_knife_leg from a piece of 1" aluminium tube.
I'll enclose a postscript file which tries to illustrate what I 
mean. (It does not conform any engineering standards).
On the left there is two cross sections, then the leg alone, and
on the right the leg and soldering iron together (40W Weller
as you can clearly see!).

The gap in ring of the leg is for the power cable, and then
you just push the iron so it comes "tight" with the leg.
Bend the leg so that you will have seam wide spacing with
the tip. That's it. It takes 1.5 seconds to put the leg on or
to take it off. 

Hope you understood my clumsy specification.
