|If you like shaped waistbands for trousers this may be of interest. In order to reduce the bulk at the end of the waistband, you can change the pattern slightly. Elongate the top band pattern at the cf by a couple of inches, and reduce the under band pattern by the same amount. The top piece is folded back and the seam displaced to a couple of inches back from the end.
This reduces the bulk where the waistband overlaps for the fastening and makes it easier to get a neat end. The band now finishes in a fold, instead of a seam.
the photo shows the top waistband pattern piece underneath the under waistband pattern piece. I've folded the top waistband piece where it will be folded when made up, so as to show that it lines up with the underwaistband piece. This pattern is for a waistband which has a centre back seam, so I've shown the right side pieces only. cb seam is to your right as you look at the photo, fold to the left, seams are shown with notches. You can see that the seam joining the top and under waistband pieces is not now at the end, where it clutters up the fastenings, but part way towards the side seam, on the inside (under) waistband. Effectively the top waistband piece has a bit of the under waistband added to it.
