If you like to sew your projects quickly, this is a great technique for waistbands, anchoring facings, and probably many other things. You can also stitch-in-the-ditch when you do machine quilting to sew the layers together. There are stitch-in-the-ditch feet available, but why buy something extra when you have a blind-hem foot to do the job already?
How to Stitch-in-the-Ditch with Your Blind-hem Foot
1) Sew the waistband onto the garment RS together. Press, then press the waistband and seam allowance upwards. If you are adding elastic, put it in now, sitting in between the seam allowance and the waistband.
2) Neaten the raw edge of the waistband. Fold down the rest of the waistband’s fabric so that it covers the elastic, keeping the raw edge down. The upper photo on the left is what it looks like on the inside of the garment, and the one below it is what it looks like on the outside of the garment.
3) With the waistband pointing towards the left, put it under the presser foot. I have it this way around because the little kink in the guide bar makes it harder to get in the ditch if it is the other way around.
Move the needle (or the guide if you have an adjustable Blind-hem foot) so that the needle goes right into the ditch. On my Brother sewing machine, this is at 2.5mm from the left on a straight stitch. Sew along the ditch until you get to the end.
If the stitch is still a little visible on the RS, slightly roll the waistband fabric down to cover it, and press.
The photos below show what it looks like when you have finished. The top photo is what it looks like from the RS. It’s nearly invisible. The photo below is what it looks like on the inside of the garment. Since this is a sample, I didn’t neaten the raw edge.
