So I ended up using to cover the sewing machine, just by fluke it fit:
- This was a good learning project but it would've been nice if I'd known more about what size to make the bag.
- A thicker and stand-uppish fabric would be better, maybe something quilted?
Since then, I've found this tutorial: Lazy Girl's Tutorial on Box Bottoms which includes some dimensions. This one is a little bit different because you have to actually cut the fabric.
