7 Best Waxed Threads For Attaching Buttons Reviewed
Discover the top 7 waxed threads for durable button attachment. We review strength, fray resistance, and ease of use to help you perfect your sewing projects.
Nothing ruins the satisfaction of finishing a hand-knitted cardigan faster than a button that pops off after a single wear. As fiber artists, we spend dozens of hours on tension and gauge, yet we often overlook the humble thread that keeps our closures secure. Choosing the right waxed thread ensures your hard work stays fastened, providing the necessary grip and abrasion resistance that standard sewing thread simply lacks. This guide explores the best options to ensure your buttons remain exactly where you intended them.
Fil Au Chinois Lin Câblé: The Gold Standard
When you handle Fil Au Chinois, you immediately feel the difference of a heritage product. This French linen thread is the industry benchmark for a reason, offering a round, consistent profile that passes through button shanks with zero fraying.
The secret lies in its long-staple flax fibers, which are meticulously twisted to prevent the untwisting common in cheaper alternatives. For a heavy-weight wool sweater, this thread provides the structural integrity needed to support the weight of the garment without stretching over time.
While it comes at a premium price, you are paying for reliability that lasts for decades. If you are finishing a heirloom-quality piece, this is the thread you want in your needle.
Ritza Tiger Thread: Unmatched Durability
Ritza Tiger Thread is a braided polyester cord that has become a staple for those who prioritize sheer strength. Unlike twisted threads, the braided construction means it will not unravel even if it is nicked by a sharp button shank.
Because it is synthetic, it is virtually immune to the moisture and rot that can affect natural fibers in high-wear areas like cuffs. I often recommend this for outerwear or heavy-gauge wool coats where the button is subjected to constant tension and friction.
The trade-off is that it has a slightly plastic feel compared to linen. However, for a button that absolutely must stay put, the trade-off is well worth the peace of mind.
Maine Thread Company Waxed Cord: Best Value
Maine Thread Company offers a fantastic balance of quality and accessibility for the everyday knitter. Their waxed cord is consistent, easy to work with, and comes in a wide variety of colors that can match almost any yarn palette.
If you are a prolific knitter who finishes several sweaters a year, buying a spool of this is a smart move. It grips the button shank firmly, and the wax coating ensures that your knots don’t slip while you are securing the final tail.
It is slightly thicker than fine sewing thread, so ensure your buttonholes are large enough to accommodate the slightly bulkier stitch. It is a workhorse thread that won’t let you down.
Vinymo MBT Thread: Superior Stitch Quality
Vinymo MBT is a bonded nylon thread that feels incredibly smooth and refined. It is designed to glide through fabric and button shanks without the "drag" that can sometimes cause thinner, uncoated threads to snap.
For delicate knits or finer-gauge projects, this is my go-to choice. It doesn’t add unnecessary bulk to the button attachment, keeping the profile clean and professional.
The bond prevents the thread from fraying, which is a common frustration when threading a needle multiple times. If you struggle with thread tangling during the sewing process, the MBT coating will be a welcome relief.
Tandy Leather Waxed Thread: Best for Beginners
If you are new to the world of heavy-duty threads, Tandy Leather is a great place to start. It is widely available and very forgiving, making it perfect for practicing your button-sewing technique without breaking the bank.
The wax is applied generously, which helps the thread hold its shape as you create your wraps around the button shank. This "tackiness" is incredibly helpful when you are first learning how to anchor a button properly.
Keep in mind that the heavier gauge might be too thick for very delicate lace or fingering-weight garments. Use it for your sturdier, worsted-weight projects where a bit of extra thread presence is acceptable.
Amy Roke Poly Thread: Professional Grade Choice
Amy Roke has gained a cult following among makers who demand a specific, high-end aesthetic. This polyester thread is designed to mimic the look of traditional linen while offering the superior performance of modern synthetics.
The color range is exceptional, allowing for precise matching to hand-dyed yarns. It lays flat against the fabric, which is essential for a clean, professional finish on the front band of a cardigan.
It is a bit stiffer than other options, which makes it excellent for creating a very rigid, secure shank. It is an investment, but one that reflects in the overall polish of your finished project.
Waxed Irish Linen Thread: The Traditional Pick
There is something undeniably satisfying about using traditional Irish linen. It has a beautiful, matte finish that blends seamlessly with natural wool fibers, unlike the subtle sheen of synthetic threads.
Linen is incredibly strong and has very little stretch, ensuring your buttons stay at the exact height you set them. Over time, the wax wears in, leaving a secure, natural-fiber bond that feels right at home on a classic gansey or wool sweater.
Because it is a natural fiber, it can be slightly more prone to fraying if you are rough with it. Use a shorter length of thread to avoid wear and tear as you pass the needle through your work.
Why Waxed Thread Matters for Secure Buttons
Standard sewing thread is often too thin and slick to hold a button firmly on a knitted fabric. Knitted structures are inherently elastic, which means the thread is constantly under stress as the fabric moves and stretches.
Waxed thread provides the essential friction needed to grip the button shank and the surrounding stitches. The wax acts as a lubricant during the sewing process but sets firmly afterward, locking your knots in place.
Without that wax, you will find yourself re-sewing buttons every few months. Investing in the right thread is essentially an insurance policy for your finished knitwear.
Selecting the Right Weight for Your Garment
Matching your thread weight to your yarn weight is a detail often missed by beginners. If you use a heavy-duty cord on a fine fingering-weight baby sweater, the thread will look out of place and potentially damage the delicate stitches.
For fine-gauge knits, look for thinner, bonded threads like Vinymo MBT. For chunky, cold-weather sweaters, you can safely use heavier, more robust cords like Maine Thread or Fil Au Chinois.
When in doubt, pull a small length of the thread through a spare swatch of your project. If it creates a large hole or distorts the stitch, it is too heavy for that specific application.
Pro Tips for Knotting and Securing Buttons
Always create a "shank" when sewing buttons onto knitwear to allow the fabric to sit properly under the button. Wrap your thread around the base of the button several times before tying off; this prevents the button from pulling tight against the fabric and causing a dimple.
When tying off, use a double knot and secure it with a tiny drop of clear nail polish or fabric glue if you are worried about slippage. Always bury your thread ends inside the fabric layers to keep the back of your work as tidy as the front.
Finally, remember that the most secure button is only as strong as the anchor point. Always sew through the "V" of the knit stitch rather than just the surface loops to ensure the button is supported by the structural integrity of the yarn.
Taking the time to select a high-quality waxed thread is a small but critical step that elevates your knitting from a hobby to a true craft. Whether you prefer the traditional feel of Irish linen or the modern reliability of braided polyester, the right choice will keep your buttons secure for years. Don’t let your hard work be undone by a cheap thread choice; treat your buttons with the same care you gave your gauge swatch. Happy sewing, and may your buttons always stay exactly where you leave them.
