Home Sewing Tips from the 1920s - Trimming a Smart Frock with Fabric Disks

This tip reminds me of bottle cap covers - which this most definitely is not. Flat circles of bias fabric are sewn and them joined to create attractive trim for your "late spring and early summer frock" of flat crepe.

I like the effect on the sleeves, though I'm not sure if trimming the skirt has the same charm. Thoughts?
