Here's my two cents-take it for what it's worth, I'm no expert
I would try aa longer length. If you are using the figure 8 to fold experiment with your angles-a flatter "x" if that makes sense. Also, to get a good crease-I always sew my bows. I NEVER could use the figure 8 to look *right* for me-I have to mark and fold
Good luck-practice, practice, practice! My first ones looked similar to yours, you can look in my shop to see what mine look like now.
