Join the Metric Measurement Cult

Japan, like most of the world, uses the metric system. So for sewing patterns, you get seam allowances of 1 cm instead of 3/8 inch. That’s nice. Can do. It’s part of the whole cult experience.

But cutting out there fabric for Straight-cut Tiered Skirt, I decided to break out the ol’ American quilting rulers and rotary cutter. Why not, since the pattern pieces are just a bunch of rectangles in various sizes.

All went along all right until it got to some odd seam allowance math. My quilting ruler measures by the 1/4 inch. When adding 3/8-inch seam allowances, it got a bit funky. 3/8 + 3/8 is 6/8, or 3/4. So far, OK. But 3/8 + 3/8 + 3/8 is 9/8, which is just stupid.

I called it an inch and got on with my life. Remember, the Doomsday Clock is ticking ticking ticking.

Here’s what the math look like for my size. I am cutting a 14 since I have pretty wide hips:
