Lapped zipper Application
Lapped zippers are the most popular of all zipper applications on garments. I think the reason is that in a lapped zipper you have a small (false) covering over the zip – so “no exposed zipper teeth”; the zipper opening is concealed very well from all and sundry – the best type of zipper application for most clothes if you do not want to show off your openings.
This lapped effect is an effect created by a creative sewing technique – the lapped zipper sewing technique.
Lapped zipper application is the most favored zipper attachment for side seam openings and for back of the dress openings and even for skirt openings.
How to sew a lapped zipper – 2 best ways
Sewing Lapped zipper without a seam opening
Take your bodice and mark the area you want to attach the zipper – measure this length
Cut out a piece of facing piece measuring 3 inch width and length equaling the zipper opening length plus 2 inches.
Mark the center line on the facing piece – equaling the zipper length.Mark 1/4 inch to either side of this line , tapering to meet the center line at the bottom edge – see the picture below.
Keep the facing piece on the right side up bodice. Pin or baste stitch in place.Sew over the stitching line you have marked – the center line is the cutting line – your sewing line should not touch this cutting line at all.At the bottom edge make a single stitch across- this is to make the cutting to the tip easy and thus enable smooth turning out.
Cut through the cutting line.
Turn the facing to the back side.Pin in place or baste stitch in place.
Keep the zipper on the back of the garment on the left side and top stitch in place.Use zipper foot as you sew this
Now bring the other edge over the zipper opening and pin in place.Then stitch along the edge a little to the inside, catching the zipper edge and the garment. This edge will be placed over the zipper opening – giving that lapped effect.
Finish the neckline with bias tape.
