I just finished the first block for my daughter's quilt. It is a pixelated heart made of various pink/red fabrics with a black background.
I am using 1.5" squares. Each block will have 289 of them.
I was going to try the fusible webbing trick and I'm so glad I didn't. I just lined up my little squares, stitched them into rows and used pins when putting the rows together.
I did use a "leader" before each round of piecing.
It wasn't nearly as dramatic as I thought. I was just worried because I haven't done something so small and complex before.
I think some of us have a tendency to overthink these things and let fear of failure rule us for a bit
