Browsing around on “Groovy Green” this morning I found links to a couple of neat ideas for using those ubiquitous single serving water bottles. I personally don’t buy them often, and hate the fact that they don’t have a deposit in the state of NY. Sigh.
Here is a neat instructable for making a self watering seed starter/planter out of a water bottle. Of course, you could probably do something similar out of a 2 liter type bottle, covering the exterior somehow. . . *
There is a photo of a plastic waterbottle cover made out of felt that turns it into a vase. This looks like it would be pretty easy to make-but you might have to weight down the water bottle with some gravel or something for stability.
Make.com has a long list of ideas for recycling water bottles-including one for using a bottle to keep your yarn from tangling that caught my eye:

Hope you enjoy browsing around!
*hmmm-notice all that neat stuff listed in the sidebar under “related ideas”. . . “colander hydrophonics”, “easy cheap earthbox”, “how to save water in the garden”. . . I could spend a lot of time around here.

Great ideas. They also make good children’s banks, crafts (such as as toy phone),lotion bottle to decorate for gifts and more. Annette
Good ideas!
