Water soluble thread. Perfect for basting and applique. Not recommended for swimsuits... LOL
Vanish water-soluble thread is created from a special blend of ingredients that allows the thread to be sewn or quilted and when immersed in water, dissolve. Vanish is available in two versions, Vanish-Lite is for sewing on home sewing machines and Vanish-Extra is for quilting on longarm machines. We recommend that you immerse your quilt/project to allow Vanish to thoroughly dissolve. Warm water will speed up the time for Vanish to dissolve.
Charlotte's Fusible Web
40 wt. melting nylon thread. Designed for fusible applique
Charlotte's Fusible Web has been designed specifically for applique. Instead of using fusible web or stabilizer that goes stiff once fused to fabrics, fusible thread allows the appliqued piece to stay soft and supple. Charlotte’s Fusible Web will melt when exposed to temperatures ≥ 250° F. Sew a single outlining stitch of the applique piece with fusible thread in the bobbin and MonoPoly on top, place the shape on the base fabric, iron, then finish with decorative stitching or invisible stitching to permanently secure the applique shape to the base fabric. Wind a bobbin with fusible thread. If exposed to the metal plate of a hot iron, fusible thread will melt and stick. This is why we recommend MonoPoly as the top thread and Charlotte's Fusible Web as the bobbin thread.
