How To Sew A Prickstitched Zipper Application
A prick stitched zipper finish is applied by hand and can be used with most conventional zipper applications such as a lapped or centered zipper. Start by stitching the zipper to the garment opening following as you would with any regular application.
1. From the right side of the zipper application, hand baste the zipper's placket line through the garment and zipper tape layers underneath. This hand basting stitch should be applied at the exact shape and location of the final zipper placket.
2. Open the zipper fully as this will make it easier to handle during the stitching process. Starting at the top edge, stitch a few times in place within the seam allowance area to lock the threads, then take a longer stitch through the garment and zipper tape layers, inserting the stitch right along the hand basted line as shown above. About 3/8" length should be sufficient for this stitch although you can apply it closer or father apart as desired.
3. Stitch back through the space cerated by the initial stitch at about 1/16"-1/8", then bring the needle back out at the same distance in front of the initial long stitch applied in Step 2 above. Pull the thread through to create the first prick stitch- this should resemble a short dash line.
4. Continue stitching back then forward again following the same distance and proportions between the stitches. Equally spaced dash line should form. Follow the hand basting line as guide, stitching next to it but not directly on top of it.
5. When arriving at the bottom, pivot the prick stitch horizontally (following the hand basting) and continue to stitch in the fashion until you arrive at the seamline. At this point, pull the thread to the wrong side of the garment and stitch in place a few times to lock the threads.
6. Once complete, remove all hand basting with a seam ripper. Left behind should be an evenly positioned, straight prickstitch constructed of evenly sized dash stitches positioned at an equal distance from one another.
