Hi all,
I'm currently working on a small 20-30 liter pack for myself. I intend to use it mostly as a daypack, or an overnight pack if it turns out bigger than expected. Everything is coming along fairly well so far. I'm not using any patterns, but I'm loosely basing the design from some of Zimmer's packs.
What I need is some guidance on forming the bottom of the pack. I've got the back, sides, and front panel all finished. However, I'm not exactly sure how to form the box like shape for the bottom.
Here is what I'd like to end up with for the bottom.

Thanks!!
