I have the beetle type zig zagger with cams and I just love it.
I have purchased the extra cams and I have gotten some lovely stitches from mine.
I am using it on my Singer 201.
I have experimented a little and found I must sew slowly and guide the fabric more closely to where I want the stitches to be.
I am thrilled with mine.
I just acquired the hemstitcher and blindstitch attachments.
Looking forward to experimenting with them and using them in my sewing.
Blessings,
Sandi
