The Hex n More ruler from Jaybird quilts is one of our favorite tools!
In this ruler you have 4 shapes the jewel, the hexagon, the half hexie, and the 60 deg. triangle.
Each of the shapes is in 4 sizes 2 1/2″, 4 1/2″, 6 1/2″ and 8 1/2″.
There are lots of patterns using this fun ruler but you can also experiment with the shapes and they all go together.
