I’m trying to find a good plastic to use to make templates out of that I can also use as cutting guides. I’d like it to be fairly substantial (1/8” or so) and able to be used as a cutting guide as well. I would be using them to cut lining fabric, not leather, so it wouldn’t be important that I could get the cut super precise. If anyone has used a specific type of plastic for this application, or if you have any informed ideas, that would be great! Links to suppliers would also be helpful!

Does it have to be plastic? I find 3mm MDF good for pattern shapes. I can cut it with a heavy duty craft knife. If it needs to be plastic, corrugated poster plastic. Here its used for politicians pre-election posters. Shops use it as well and it can be got cheaply from them (usually it is thrown away after use) or directly from a printer of posters.

Clear acrylic is often used and has the advantage of being able to be seen through as you use it. Laser cutting makes this a quick and easy job but alas if it is a small diode laser normally they will only cut black or red colours and not clear. If you can say what state or town in the world you are in it would help others to suggest where you can get it and who could cut it etc. It is very available all over the world but the sheets are large and it is usual to get the sheets cut to a size you want locally. Here in Rockhampton I have a supplier that cuts what I want to size and I can laser cut the finer stuff after myself.

Thank you for the suggestions! I could certainly use MDF, but didn't want to worry about cutting away at it when I'm running my knife along the side. Is there much of a problem with this from your experience? I was thinking a soft plastic like that used in corrugated signs would have the same issue.

I'm in the US. I was thinking of just getting a sheet of the stuff and cutting it with a miter saw (the templates are just rectangles). Amazon.com has sheets of acrylic, polypropylene, mylar, ABS, and other such things. I just have no idea what the qualities of any of these are. Perhaps there is a plasticworker.net that I should consult. :D

a. I use both 3mm clear acrylic, which is cut to my requirements by a company, and 3mm MDF also cut by them or me

b. Most times I just trace around the template and cut with a knife or shears along the marked line. If I have to I will cut using the edge of the template as a guide and with care I've never taken any slices out of a template yet

c. I think to be totally free of that threat you'd need a template made of hard metal, like steel, as you can still take a slice from the edge of aluminium

d. Unless you need to see through the template I'd recommend 3mm or 6mm MDF. Its much cheaper and easier to get

My buddy and I have been looking for the same thing over the past couple of days. 

A friend got me a sheet of 5 mil clear acrylic from someplace in Carson City, but I can't run that down. 

It looks like Lowes might have what we need, but since we both live out here in the weeds, we won't get to town to check it out until near the end of the week.  I'll report back.

You might consider TAP Plastics. They have stores throughout California, plus they have a great website. I've found them very helpful.

How large do you need the template to be?

Hey there, Mr. Bags. That'd be great! Let me know.

Hey Fred. Thank you, that does help. As I said before, I'm not cutting some thick leather or anything, just some nylon lining fabric fairly imprecisely I might add. So MDF might be the best choice. I'll have to do some intense head-scratching however, and convert your European milometers to good 'ol inches. :D

a. 3mm = 1/8 inch,   6mm = 1/4 inch - close enough for government work, :P

b. I use a big heavy weight on the template to hold it down

c. I suggest you use a rotary knife on thin material
