Invisafil Solid 100 wt Polyester Thread by Wonderfil

400m, 100wt, 2-ply cottonized polyester thread.

This ultra-fine but surprisingly strong thread has cotton-like characteristics and feels soft in the hand. InvisaFil makes for super low bulk stitches that virtually “disappear”, making it the ultimate choice for English paper piecing, hand applique, delicate lace designs, fine fabrics, creating texture when micro quilting, or whenever you don’t want your stitching to show.
