My son and I found a piece of tyvek while out on a nature walk/roll yesterday. It's dirty and has some holes it so I need to clean and trim it before I know exactly how much I have.

My immediate thoughts were to make a tarp or ground sheet with it if it's big enough and stuff sacks if it isn't.

I haven't used tyvek to make anything before and wondered if the ETS brain trust had any other suggestions for projects or tips for working with tyvek?
