Superior Threads MonoPoly Smoke Spool

Superior Threads MonoPoly in Smoke is a fine-gauge, reduced-sheen polyester monofilament thread designed to disappear into your fabric. At 100 weight and just .004 inches in diameter, it is ideal for quilters and sewists who want secure, nearly invisible stitching for appliqué, quilting in the ditch, and binding work on dark or neutral-toned fabrics. The smoke colorway blends naturally with medium to dark fabrics, making it the go-to choice when you want your stitches to do their job without drawing attention.

Key Features

• Reduced-sheen finish gives MonoPoly a matte appearance that mimics the look of natural fiber thread rather than standard shiny monofilament.
• Ultra-fine 100-weight construction at .004 inches (0.1mm / 90 denier) allows the thread to sink into fabric layers without adding bulk.
• 2,200-yard spool provides generous yardage for large quilts, ongoing projects, and frequent sewists who rely on invisible thread regularly.
• Polyester fiber construction offers strength and durability while remaining flexible enough for dense quilting and appliqué applications.
• Smoke colorway is specifically formulated to blend with medium, dark, and multi-toned fabrics where a clear monofilament would appear too visible or reflective.
• Recommended for quilting and invisible appliqué, making it a versatile addition to any thread collection focused on clean, professional finishes.
• Compatible with home sewing and quilting machines — use in the needle for invisible stitching or in the bobbin for reduced thread show-through on quilt backs.

Frequently Asked Questions

What is MonoPoly thread and how is it different from regular monofilament?

MonoPoly is a polyester monofilament thread with a reduced-sheen finish, which gives it a matte appearance rather than the shiny look of traditional monofilament. This makes it far less noticeable in finished work, particularly for quilting and appliqué where you want stitches to blend into the fabric.

When should I use the smoke color versus the clear color?

Smoke is best suited for medium to dark fabrics, where a clear monofilament would appear too bright or reflective. For light to white fabrics, the clear colorway of MonoPoly is typically the better match. When working with multi-colored or predominantly dark quilt tops, smoke tends to disappear most effectively.

Can MonoPoly be used in the bobbin as well as the needle?

Yes. Many quilters use MonoPoly in both the needle and the bobbin, though some prefer to use a lightweight cotton or polyester thread in the bobbin to reduce cost and simplify tension adjustments. Because MonoPoly is very fine (100 weight), it tends to behave well in most home machine bobbins — refer to your machine manual for any monofilament-specific guidance.

Is this thread compatible with my Janome, BERNINA, or bernette machine?

MonoPoly is compatible with most home sewing and quilting machines, including Janome, BERNINA, and bernette models. Because it is very fine, you may need to adjust upper thread tension slightly — typically reducing it — to achieve a balanced stitch. Start with a test sample and adjust as needed for your specific machine and fabric combination.
