Stage Two Failed...Try Again.

Today I dragged out my sewing machine and got everything together to assemble my Space Invaders bag. As I was cheerfully threading my needle I glanced at my cut fabric and came to a sad realization:

When you square the bottom of a bag, the width of the bag decreases as part of the width becomes the sides. I had not accounted for this decrease. Which means that my bag doesn't have sides. I thought about the logistics of using my strap as the side, and this seemed to be a good idea until I got my tape measure, did a bit of pretzel-like twisting and figured out that the resulting strap would be too short for my purposes.

Since I have no fabric left, it's off to Fabricland on Monday.

This is the second bag I've attempted and the second one with "issues". I think the universe is trying to tell me something...
