Love these plastic bottle crafty ideas. This would be great to do with the family and incorporate it into the family outdoors....put the pigs next to the garden area...the elephant and frog would go good by the pool garden and the frog could also be by the pond. They'll enjoy it more as they walk pass/through it.
Plastic milk jug butterflies - I love this idea! Reusing milk jugs instead of using shrink plastic sheets is a great way to create while reducing waste and keeping away from the oven. Check out http://alphamom.com/family-fun/crafts/milk-jug-decorative-window-crafts/
