Suitable closures for these fabrics include invisible zippers if the fabric is not too bulky, hand-picked zippers, buttons and buttonholes, loops, covered snaps, or hooks and eyes. For my sample jacket, I followed the pattern directions to insert large hooks and eyes as a closure. When stitching the closure bands in place I left 1/4" openings, which allowed me to insert the hooks and eyes. The hooks and eyes were then hand sewn to the garment seam allowances and I took a couple of small stitches to close up the openings. I stitched in the ditch to hold the layers of the under placket together and to prevent them from pulling apart when worn. I hand-stitched the overlay placket together with the garment to prevent it from pulling. I used fine silk thread in a matching color and working from the right side of the garment I did a tiny backstitch through the layers. My backstitch was over one thread of the garment so it was invisible and the length between the stitches was approximately 3/8". The texture of the fabric allowed me to hide my stitches very well.
Dry cleaning is recommend for most of these specialty fabrics.
