Do you have the manual for your machine??? I would try lengthening the stitches a little if you think they are too small. It could be just needing a minor adjustment...I kept notes by my machine on what settings I used for stitch lengths, tension settings etc... that way if they got moved or I need to change them when I sew something different, I don't have to guess or depend on my memory :roll: to get the perfect stitches again :wink:
