Julie, half square triangles aren't the monsters I used to fear too. Just like everything else here, there are tips and techniques to learn. Once you have them down, the world of new patterns is wide open to you. Try using the pattern on some scrappy fabrics to get used to the technique that came with the pattern. Then try the class. Then try a tutorial on here. (Or whatever order you choose). You'll be SO proud of yourself once you whip triangles into shape.
