Monofil Transparent 40wt Threads at Linda’s Electric Quilters features Amann Group’s Monofil monofilament thread in the versatile 40-weight format — designed to create invisible or near-invisible stitching that blends into any fabric color. Monofil is the professional quilter’s choice for applique, stitch-in-the-ditch, and hemming applications where the thread should disappear completely into the finished work.
What makes Monofil 40wt different from lighter monofilament threads?
At 40-weight, Monofil provides a slightly more substantial thread body than ultra-fine monofilament options, making it easier to handle in the needle and bobbin while still creating stitches that are nearly invisible in the finished project.
Can Monofil 40wt be used in the bobbin as well as the needle?
Yes — Monofil can be used in both needle and bobbin for completely invisible stitching on both sides of your quilt or project. Adjust tension carefully when using transparent thread in both positions.
What colors is Monofil 40wt available in?
Monofil transparent thread is available in clear (for light and medium fabrics) and smoke (for dark fabrics). Using the right version for your fabric color creates the most seamless, invisible result.
Is Monofil 40wt safe for quilts that will be used by babies or children?
Quality monofilament threads like Monofil are made from soft, non-scratching polyester that is safe for use in quilts for babies and children when washed and cared for properly according to the manufacturer’s instructions.
