When sewing a bound pocket application, the longer pocket bag layer is folded over the slash pocket to form the welt-like pocket opening. The edges should be folded at an even distance throughout with the folded edges perfectly abutting at the pocket opening. While ironing will go a long way in evenly creasing each fold, the two folded edges tend to shift way form the center of the pocket opening which can make the remaining construction process quit uncomfortable.
Sewing Tip: You can use a temporary hand- applied whipstitch to keep the bound pocket opening edges aligned and stable in the construction process.
With the pocket opening closed, the pocket bag layers are comfortable to align and keep flat in the alignment and stitching process.
Once the bound pocket application is complete, the whipstitching is easy to remove with seam ripper.
Use a hand-applied temporary whipstitch with any slash pocket application that require extra stability at its opening.
