I'm making Simplicity 3762 (
http://www.simplicitynewlook.com/images/3762.jpg) on my brand-new Babylock. I'm trying to figure out how to use the machine as I go along, and so far it's going ok except the elastic. In addition to the elastic in the waist, there is this crazy elastic that's supposed to gather the inside sleeves and side seams. This is what I have tried (on scrap pieces) so far:
1) Applying the elastic as the seam is sewn. It seems that even with the differential feed set at 2, it still doesn't stretch the elastic properly.
2) Applying the elastic after the seam is sewn, using the chain stitch and stitching in the ditch from the right side. I have an elastic foot but it apparently can't be used to apply elastic to the bottom side of the fabric, and I don't want the chain side on the outside for aesthetic reasons.
I went ahead and serged the seams anyway, thinking I'd apply the elastic later on my regular machine, but I'd rather figure out how to use the serger for this.
Any ideas?
