6 Best Bias Tape Makers For Custom Knitwear Trim
Elevate your knitwear with precision. We review the 6 best bias tape makers to help you create professional, custom trims for all your handmade garments.
Adding a custom fabric trim to a hand-knitted garment is the professional secret to transforming a "homemade" piece into a high-end heirloom. While many knitters rely solely on yarn-based edgings, integrating fabric bias tape provides essential structural stability to necklines and button bands. These six tools simplify the process, allowing you to create perfectly uniform strips that mimic the drape of your favorite knitwear. Mastering this technique will ensure your cardigans and sweaters maintain their shape through years of wear and washing.
Clover Fusible Bias Tape Maker: Best Overall
The Clover Fusible Bias Tape Maker is a game-changer for knitters who struggle with the "wobbly" edge of a stretchy sweater. By incorporating a heat-activated adhesive, this tool allows you to fuse your trim directly to the garment before you even pick up a sewing needle.
It is particularly effective for stabilizing necklines that have a tendency to sag after heavy use. Because the adhesive is built into the tool’s output, you get a clean, crisp finish that prevents the fabric from shifting while you work.
The primary tradeoff here is the heat required; you must ensure your chosen fabric can handle the iron temperature needed to activate the glue. If you are working with delicate fibers like silk or fine wool, always test a swatch first to avoid scorching.
Dritz 25mm Bias Tape Maker: Best for Beginners
If you are new to sewing fabric trims onto your knitting, the Dritz 25mm maker is the most forgiving entry point. Its simple, intuitive design allows you to feed your fabric strip through the slot and press it into a perfect fold with minimal frustration.
The 25mm width is a "Goldilocks" size for most adult-sized sweaters, offering enough surface area to grip both sides of a knitted edge securely. It is straightforward, durable, and lacks the complex moving parts that often lead to mechanical failure in cheaper knock-offs.
Don’t be tempted to force thicker fabrics through the slot, as this will cause the tool to jam or create uneven folds. Stick to lightweight cottons or rayons, which provide the best balance of structure and drape for knitwear applications.
Simplicity Adjustable Bias Tape Maker Tool
Knitting projects vary wildly in weight, from airy lace-weight shawls to chunky, heavy-gauge sweaters. The Simplicity Adjustable tool is the only one on this list that accommodates multiple widths, making it the most versatile choice for a diverse stash.
Instead of buying a new tool for every project, you simply slide the dial to adjust the width of the fold. This is an excellent investment for the knitter who frequently switches between different yarn weights and needs matching trim widths.
The learning curve is slightly steeper than fixed-width makers, as you need to ensure the dial is locked securely before pulling your fabric through. Once you find your rhythm, however, it saves significant storage space in your knitting bag.
Prym Bias Tape Maker for Precise Finishing
Prym is renowned for its precision engineering, and their bias tape maker is no exception. If you are a perfectionist about your button bands or collar edges, this tool offers the most consistent, sharp-edged results available.
The metal construction feels substantial in the hand, and the feed mechanism is remarkably smooth. It excels when you are working with slippery materials like silk or rayon, which often slide out of place in plastic tools.
Because it is so precise, it is less forgiving of "wonky" cutting. You must ensure your fabric strips are cut perfectly on the true bias—at a 45-degree angle to the grain—to get the best performance out of this specific tool.
Washi Bias Tape Maker for Delicate Fabrics
When you are adding a trim to a fine-gauge, luxury knit—like a cashmere sweater or a baby garment—the bulk of traditional bias tape can be overwhelming. The Washi maker is designed specifically for finer, more delicate fabrics that require a lighter touch.
This tool creates a very narrow, refined fold that won’t distort the drape of your knitting. It is perfect for creating delicate piping or internal seam finishes that need to be soft against the skin.
Avoid using heavy-weight quilting cottons with this tool, as the narrow channel will cause the fabric to bunch. Pair it with lawn, voile, or silk for the most professional, high-end result.
Hemline Bias Tape Maker: Best Value Option
The Hemline maker provides a reliable, no-frills experience that gets the job done without breaking the bank. If you are only planning to add trim to one or two projects a year, this is the most practical purchase.
It is lightweight and portable, making it easy to toss into your project bag for a weekend retreat. While it lacks the advanced features of the Clover or Prym, its simplicity is its greatest strength.
The plastic can be prone to wear over many years of heavy use, but for the casual knitter, it is a perfectly adequate tool. It performs exactly as advertised, providing a clean fold every time.
Why Custom Bias Tape Elevates Your Knitwear
Custom bias tape acts as a "skeleton" for your knitting, preventing the dreaded "growing" effect that happens when a sweater stretches under its own weight. By choosing a fabric that complements your yarn, you add a layer of durability that yarn alone cannot provide.
It also allows you to introduce color, pattern, or texture that would be impossible to achieve with knitting needles. A floral cotton trim on a solid-colored wool cardigan creates a sophisticated, boutique-quality look.
Ultimately, the goal is to bridge the gap between the flexibility of knit fabric and the structure of woven fabric. This hybrid approach is the hallmark of a truly skilled maker.
Selecting the Best Fabric for Knit Trim
Choosing the right fabric is just as important as choosing the right yarn. You want a material that has similar care instructions to your yarn; if your sweater is machine-washable wool, do not use a fabric that requires dry cleaning.
- Cotton Lawn/Voile: Excellent for lightweight sweaters; breathable and soft.
- Silk: Ideal for luxury garments; adds a beautiful sheen and minimal weight.
- Rayon: Great for drape, but be careful as it can stretch more than cotton.
- Linen: Adds a rustic, crisp structure but can be prone to wrinkling.
Always pre-wash and dry your fabric using the same method you intend to use for the finished garment. This prevents the trim from shrinking later and pulling your knitting out of shape.
Essential Tips for Pressing Bias Tape
Pressing is the stage where most knitters lose their way. Use a high-heat iron setting for cottons, but always use a press cloth when working with synthetic blends or delicate fibers to prevent melting.
Use the tip of your iron to "chase" the bias tape as it emerges from the tool. By pressing the tape immediately as it comes out of the maker, you "set" the fold, ensuring it stays crisp and doesn’t unravel before you sew it on.
If you are struggling to keep the tape flat, use a starch spray before feeding the fabric through the tool. This gives the fabric extra body and makes it much easier to handle.
Troubleshooting Common Bias Tape Issues
If your tape is twisting or coming out uneven, your fabric strip was likely not cut on the true 45-degree bias. Always use a rotary cutter and a clear quilting ruler to ensure your strips are perfectly straight and consistent in width.
If the tape is bunching up inside the tool, you are likely using fabric that is too thick for the channel. Try a lighter-weight fabric or move up to a larger size bias tape maker to accommodate the material.
Finally, if the tape isn’t staying folded, your iron may not be hot enough or you aren’t pressing firmly enough. Remember: the goal is to create a permanent crease, so don’t be afraid to apply steady, firm pressure as you move the tool along the fabric.
Integrating custom bias tape into your knitwear is a rewarding skill that marks a significant milestone in your development as a fiber artist. Whether you choose the precision of a Prym or the convenience of a Clover, these tools offer the control you need to achieve a professional finish. Take your time with the fabric selection, respect the bias, and enjoy the transformation of your handmade garments. Your future self, wearing a perfectly structured sweater, will thank you for the extra effort.
