Whatever rulers you get, you should get a couple with the angle markings on them. You will need to use angles at some point in time. I have Fiskars square rulers with angles 30, 45, and 60 degree markings. Use coupons when you can. Hexagon rulers are great. I waited to buy specialty rulers til I really wanted to start making a certain block and couldn't figure the angle on one of my rulers. Sometimes it's just easier. Good luck!
