This is something I came up with out of necessity: Drinking straw test tubes.
I prefer not to design flowers dry and include some sort of a water source even when I glue flowers into a fragile armature.
I have also used these in corsages and other body flowers. Its handy when you want to add a tiny stem into a tiny space. It is especially suitable for orchids- they are slow drinkers with thin stems. One tiny tube can keep a single orchid hydrated for days
By now I am a bit of a drinking straw collector. I know exactly where I can find the fatter straws or coloured straws. And yes, I always take my straw home with me. Up-cycling in action, I think
I even developed a special way to fill these tiny tubes really fast. Follow the link below to see my Syringe Tube Tutorial.
