The In the Shadows Filaine Petites Thread Sampler is a must-have for your thread stash! Filaine is a 12 wt. Acrylic thread that produces a stitch that mimics vintage handwork, with a nubby textured feel and appearance. Use Filaine for woolens or knits, denim, canvas, or cotton fabrics, to showcase vintage style embroideries by hand or machine, brushed embroidery designs to mimic real fur, pronounced topstitching, and big-stitch quilting.
