Enci--
These blocks are just beautiful! Iris are my favorite flowers, as you can tell from my screen name. I just have a couple of questions for you:
Do you have measurements for the size of your beginning squares?
Can you tell us how far your cuts are from the corners of your stacked squares?
Do you use a bias strip of fabric for your stem and leaf pieces?
Are the leaf pieces made essentially like the stems?
Thanks for showing us a new way to make a beautiful block!
