Given my time crunch (October 5th!) I don't have the ability to shop around to find a period appropriate thread. So I compromised and bought the polyester thread for my pretty light weight cotton fabric. : (
It doesn't pull as nicely as a natural fiber, so it's not as fun to use. The color is right so I'm making do, though I'm not crazy about it.
Have you ever had to compromise on a sewing project that you were disappointed with at the time? Afterwords were you OK with your compromise...or did the compromise ruin the project?
