The Flowering Tulips bundle makes the most amazing 3D tulips. They look a little daunting at first but you can find many places where they show you the way to compose your tulip flowers. The accompanying Designer Series Paper has some great colour combinations.
I chose the pattern of DSP that I wanted first and then made my tulips match the colours in the paper.
To add some dimension to the tulips I added ink to the die cut edges of the tulip pieces and the leaf pieces before assembling them.
