For me it is hard to cut pieces to make a shape perfect. Like the star below, I cut the pieces the right angle and right length short to long and long to short. For some reason the angle isn’t straight. I try to put them together and they don’t add up. I don’t know if it’s the saw or if it’s me but I don’t have a jig so maybe that will help. Let me know if you had the same prob and how you fixed it.
