Okay....sorry I didnt' give much detail the first time.
So I'm serging squares and before I get to the end I start to turn with the machine going slowly, the first half of the corner comes out good but the second half doesn't because the fabric doesn't feed under the pedal smoothly and I end up with bunched up fabric and the overlap fabric that should have been trimmed off by the machine is getting sewn up and over my serge line. Make sense?
I hope so....I've tried cutting the corners so they are already semi-rounded...but that's not helping.
