It is rainy in Los Angeles, CA because of the storm. Have some light weight but outdated wind breakers, many baseball caps and clothing of that sort. Just wonder if people recycling and converting them into rain ponchos using plastic bags, hot iron, hot glue gun, hot glue sticks, and parchment papers. I believe that it can be quite easy, creative, and practical.
Late, as always...Ive used foil, brown butcher paper, even an old town. They all work and you can get a different effect from each: texture, wrinkles, etc...
