the easiest way to measure around curves

I've been drafting a new bag pattern, and I thought I would show how I measure lengths around curves.  It's really quite easy.

Start by pinning the pattern piece to something soft, like a a bed or a large corkboard.  Use one set of pins right on the line you want to measure, and another set a 1/4 inch away or so.

Then run your measuring tape between the sets of pins and gently pull taut.

That's it! You don't have to make square bags anymore!
