Mylar

[Frank Weston]

Glen asks:  What is Mylar and where can one buy some?

Mylar is a Dupont tradename for a plastic film which comes in thicknesses
of up to 14 mil, with standard sizes being 3 mil, 7 mil, and 14 mil in
various lengths and widths.  Any vendor who specializes in plastics should
be able to get it for you.  Nationwide a company called Larid Plastics
carries it, but you will probably have to order a 100 foot roll.  Their 800
number is 873-8405.  You might also try Mill & Marine Supply at (334)
666-0343.  Drafting and art supply houses carry Mylar in thinner sheets,
but most of this is unsuitable for pattern making.  Mylar is also used in a
lot of high-performance sails, and in sail-makers patterns, so if you live
near a sail loft you may be able to pick up small quantities.

7mil thickness is probably best for making patterns.  14 mil is pretty
tough but more durable, and the thinner stuff tears a little too easily for
long term use.
