This is wow! Absolute zen! I’ve never seen a shelf that looks so harmonious and would be ideal without unnecessary details. These tube sheets are made of wood, felt and tubes with no steel element, and the felt holds the tubes or vases. There are different profiles that can be cut in different lengths for different arrangements. You can swap out or rearrange the tubes depending on the flowers you’re using. Each shelf comes with small and large test tubes. All of the wood used is scrap, and the shelves are made of tung oil. Perfect isn’t it?
