My fave is #16 ..... holds plant life upward .... is so useful!
As you probably heard, two years ago I constructed a new second floor with two bedrooms and a bathroom on my cottage, done entirely with high density, high strength, foam swim noodles purchased at the November, Gilford-Walmart noodle markdown ..... highest noodle quality, lowest noodle price in blue, red, and green!
