InvisaFil™ is Wonderfil's finest thread line — a luxurious 100wt, 2-ply cottonized polyester designed to virtually disappear into your stitching. With a silk-like feel and matte finish, this ultra-fine yet surprisingly strong thread delivers beautifully low-bulk results for both hand and machine work.
Ideal for English paper piecing, appliqué, micro quilting, delicate lace, fine fabrics, and invisible stitching, InvisaFil™ blends seamlessly into your projects while still offering the strength and control you need. Available in 60 subtle-to-bright solid colours, you can choose exactly how much (or how little!) you want your thread to show.
Whether you’re working on heirloom details or intricate quilting textures, InvisaFil™ gives you precision without the bulk.
