Heavy Duty Plastic - need ideas

[mzgarden]

A friend of mine does home dialysis.  Her kits come in heavy duty plastic bags.  She has been cutting the bags apart to get her kit out but then cutting out the long sides of the bags, thinking they could be used somehow instead of going in the trash.  She showed up the other day and handed me a big armload and asked me to see if I could think of something to do with them.   I'm looking for creative ideas.

The plastic is roughly cut into about 18"x24" pieces.  It's heavy and fairly stiff .  It's clear.  I'm making the assumption is NOT foodgrade so I wouldn't want to use it anywhere it would touch food.

I have been able to sew it - I played around made a bag to store an unfinished quilt top in.  I lined a little fabric bag with it and it's stiff enough it gives the bag structure.  I cut it into strips to see if I could braid it, but it's pretty stiff - I'd have to cut the strips pretty thin which I think I'll try again.  I'm able to write on it with a permanent market and wipe it off easily  - thinking I'll try sewing some to a fabric back and making a dry-erase type of thing maybe with magnets to put on a refrigerator for a grocery list?

She has a never ending supply of this stuff and is desperately looking for someone to find uses for it. 

I'm hoping some of you might have some more ideas I could play around with also.

You could sew them together (as you said), then staple them to a cold frame. We have one like the picture except it is over a raised bed, set against the south side of the garage, and it is slanted and not square (not horizontal). The plastic we buy is expensive and doesn't last more than a year anyways.

Buy plastic panels like those used over fluorescent lighting?

I also use clear and white plastic, for covering the floor for painting a room. And for putting over carpet before I put flats of dirt for onion seeds. And over the plant heating mat where we start seedlings because electricity and water don't mix well. And next to the garage entrance to the family room, in winter, to put wet boots and shoes on.
