Totes with Oval Bottoms

I had no idea I would ever need a book called the Illustrated Dictionary of Math. I now find that I actually might. I have mentioned Craft Nectar before and Weeks Ringle does not disappoint. She talks about the usefulness of this book in constructing oval tote bags. I might actually want to do that someday. You never know.

For example, did you know that the Illustrated Book of Math will give you the formula for the circumference of an oval if you’ve designing a totebag with an oval bottom?
