The BOHIN temporary fabric glue pen helps hold pieces in position before stitching, making prep steps faster and reducing the need for extra pins. The glue applies in pink so you can see placement and it disappears as it dries, which is helpful for appliqué, hems, templates, and paper piecing setups. Because fabrics vary, test on a scrap first and then stitch through the positioned pieces once you are satisfied with alignment and removal behavior.
