Welcome and wonderful stick carving! Woodcraft may have some Diamond Willow sticks. If not, it doesn't hurt to ask if they can get a supply for interested stick carvers. I know I have seen them at the Tucson location. Not sure about the Phoenix/Chandler area.

Check Woodcraft Store Locator (LINK) online. Call or email them if you haven't found anything promising yet. Good luck.
