Thanks for the great tips. However I have a problem with the tip of serging an inside curve by straightening the curve. A straight line is shorter than a curved line. If you serge an inside curve by straightening it the curve will become shorter & it that will become a problem when you're ready to attach the piece to match another curved piece... now ask me how I know... I've read other tips to overcome this problem & the best I've found is doing the same technique as with an outside curve, serging a little at a time following the curve.
I have an Babylock Evolve & I love it!!!! I just wish I had more time to play with all it's different capabilities.
