Matt from PlantTherapy (of Apartment Therapy) posted a wonderful guide on how to twist your tulip stems when making a tulip flower arrangement. The twist is a simple, modern touch that adds a beautiful and sophisticated element to your arrangement. With a little practice, I am sure you can master this design technique too!
Check out the tutorial here - it is complete with instructions and pictures to give you a good idea of what to do. A video from Martha Stewart also shows you how to twist tulips stems - they start talking about the twist around 5:30 minute mark. *I had already posted this link back in February with some more information about tulips.*
