Wow! Mine was right on. I only have 2 totes of stash and can quite easily calculate the fabric I will need to make a quilt. I hate spending too much money on tools and have very few. I just spent 10hrs total planning a simple Trip around the world for a queen bed because I wanted the blocks section to fit the center of the mattress perfectly
with the top borders section being under the pillows. It's turning out great!
