This is the easiest/ cleanest looking way to make belt loops that I have found.
coordinating fabric scraps
1. Start with a fabric rectangle. Mine is 2 1/2"x 3". This size rectangle will accommodate a 1" wide belt when finished. Increase the length (and width if desired) to accommodate the style of belt you plan to use with the belt loops.
2. If you are using a serger, serge off 1/4" from both short ends of the rectangle. If you are not using a serger, fold over each short edges 1/4" and iron flat. I did one of each to demonstrate both.
3. Fold the rectangle in half lengthwise with wrong sides together. Serge off 1/4" down the long end. Or sew with 1/4" seam, zig-zag and trim.
4. Iron flat so that the seam is in the middle of the belt loop. It will look like this on the back:
and this in the front:
5. Top stitch along both long edges to hold in place.
6. Pin the belt loop onto your clothing with one of the serged (or folded) edges down. The right sides of the belt loop and the clothing should be touching. Your belt loop will stick up like this:
**Above: You are looking at the right side of my fabric and the wrong side of the belt loop.
7. Sew the belt loop on with 1/4" seam.
8. Fold the belt loop over and iron flat against your clothing piece. Pin in place.
**Once folded, you are looking at the right side of the clothing and the belt loop.
9. Top stitch (1/8" seam) along the top and bottom of the belt loop to hold in place. I went over the seam 2 or 3 times to secure.
Now you have hassle free, beautiful looking belt loops.
