What a brave person you are! I've been quilting for years and I still stay away from diamond shapes. Reminds me of when I first started sewing clothing. I took my Mom's sewing machine home with me one weekend. Bought plaid fabric for a skirt and jacket. Read and followed the pattern, matching the plaid in the side seams and sleeves. When I showed my Mom she couldn't believe I chose plaid fabric and how well it turned out. Sometimes being clueless is the best way to learn and not be paralyzed with fear to try the more difficult patterns.
