If you have never done paper piecing, it can be very daunting at the beginning. I had to do 3 projects with it before I even started feeling like I could do it OK, let alone well.
Keep at it. As your brain grasps the "flipping" technique, you'll get better at it. I still take far longer than lots of other people I know to do a block. But I LOVE how the lines always come out perfectly straight and the intersections are such sharp perfect angles.
Don't give up....it gets better!!
