I, too, tend to cold cut fabric unless I'm cutting templates for more than
one kite. Hot cutting on glass makes it easy to put several layers of
fabric under a template and cut out patterns for several kites. If I'm
doing a single kite, I use a 54"x36" self-sealing cutting board, found at
most art supply or fabric stores and a surgical scalpel (#11 blade). These
blades are comparable to the #11 hobby razor but tend to last a bit longer.
Whatever you do, don't use them unless you have a cutting board underneath,
they tend to dull real fast if used on glass and a dull point will surely
fray the fabric.

If you get serious about building, it would be a good idea to invest in an
industrial strength hot knife, primarily used for cutting the webbing most
kites use as nose reinforcement. A friend has one and it cuts two layers of
seatbelt webbing like it was soft butter! They run over $100 but they are
a nice investment. Check with the bigger ripstop sellers, they may have one.
