[SML] Thermo plastics

ok, i tried to send this last week, but for some reason, it came out in random letters and i'm not sure why:

Hello everyone,​

My name is Will Thompson, and I am new to this mailing list, so I just wanted 
to introduce myself. i joined the mailing list as a part of my intro to stagecraft 
class at U of L. In my free time, I get into costuming and prop design/
creation, so a lot of my questions will probably be on one of those subjects. 
most of my experience is with cosplaying, but the costuming and prop-making 
requirements are pretty much the same. 

I have recently started working with polypropylene (clear storage bins from 
walmart) as a cheap alternative to other thermoplastics that is a lot more 
accessible. A friend of mine showed me that you can use a wood burning pen
to fuse the edges of the plastic together like welding and its really easy to do.
(we checked it out with the company and with chemical engineers, it is not 
harmful unless you constantly breathe it for a very long time in a single sitting)

My question is: has anyone ever done/heard of work done with polypropylene?
also, does anyone know a way to color it? I know its pretty inert, but maybe 
something like contact paper/shelf liner or if there is a way to make it hold paint?

Thanks,
Will Thompson​
