Use your blind hem foot! On Janome machines, it’s the G foot and comes in 2 styles: Fixed and Adjustable
If your machine makes stitches 7 mm wide, you can use EITHER foot. My friends with 5 mm wide machines (like my Elna STAR edition) will need the adjustable version. The narrower stitch width on 5 mm wide machines means the needle can’t go far enough left to achieve satisfactory results with the fixed style foot G.
Machine settings: Straight stitch with stitch width = 0.0 or 0.5 and stitch length = 3.0. For 5 mm wide machines, adjust the guide wheel so only 2-3 threads are showing (see picture below).
Place fabric under needle and align right side of fabric with flange on foot.
Sew at a slower speed for more uniform topstitching.
That’s it! What a timesaver on bag handles and topstitching folded edges for a more finished look!
