Hi Ric, here are some lovely ideas for plastic bottles - https://www.mnn.com/lifestyle/arts-culture/stories/10-creative-ways-upcycle-your-plastic-bottles
I recently saw where someone cut the bottom off of a bottle and painted it with chalkboard paint and planted herbs in them.
You can make braided rugs out of the plastic grocery bags. I use them for my small wastebaskets rather then buy small trash bags. I keep them in my swim bag to put my wet suit in. Always keep a couple in the car in case someone feels sick and to empty my car trash bag. I've used plastic 2 ltr. bottles with small holes punched in them for drip watering plants. I've also cut them for scoops also.
