6 Best Pin Backs For Creating Felted Brooches

Creating a stunning needle-felted brooch is only half the battle; the true test lies in how well it holds up when pinned to a favorite hand-knit cardigan or a dense wool coat. A beautiful piece of fiber art deserves a fastener that is just as reliable as the felted structure itself. Choosing the wrong pin back can lead to sagging, snagging, or worse, the total loss of a hard-earned project. This guide breaks down the best hardware options to ensure every brooch remains a permanent, secure fixture in a curated handmade wardrobe.

Standard Bar Pins with Safety Catch: Best Overall

Standard bar pins are the workhorses of the jewelry-making world for a reason. They provide a reliable, straightforward locking mechanism that keeps the sharp point of the pin tucked safely away from delicate fibers.

These pins work exceptionally well with felted pieces because the elongated metal bar distributes the weight across a wider surface area of the felt. This prevents the brooch from drooping forward when worn on softer, drapey fabrics like a loose-gauge mohair or alpaca blend.

Opt for these when a classic, invisible look is preferred. They are widely available and offer a perfect balance of security and ease of use for everyday accessories.

Sew-On Brooch Backs with Holes: Most Secure Fix

For makers who prioritize longevity, sew-on backs with pre-drilled holes are the superior choice. Sewing the metal directly into the felt creates a mechanical bond that is far more durable than any adhesive could ever provide.

When attaching these, use a strong, non-stretch nylon thread or a fine fishing line to cinch the metal backing firmly against the felt. This method is particularly vital for larger, heavier brooches that might otherwise pull away from their base over time.

Because these pins require a bit more effort to attach, they are best reserved for heirloom-quality pieces. Avoid using standard cotton sewing thread, as it may degrade or snap under the constant tension of being pinned to thick outerwear.

Dritz Flat Back Pin Backs: Best for Quick Gluing

When a project demands a quick finish, Dritz-style flat back pins offer a streamlined, no-fuss solution. The wide, flat metal surface provides a generous “landing pad” for industrial-strength glues or epoxy.

These are ideal for smaller, lightweight felted designs where a sew-on backing might be overkill. Because they are low-profile, they remain discreet even on thinner, more delicate hand-knits.

Successful use of these pins depends entirely on the quality of the adhesive. Always rough up the metal surface slightly with fine-grit sandpaper before applying glue, as this creates a better “tooth” for the bond to grip.

Heavy-Duty Magnetic Backs: Best No-Holes Option

Magnetic brooch backs are the perfect solution for knitters who fear the damage caused by piercing fibers with a sharp pin. These utilize two powerful magnets to sandwich the fabric, allowing the brooch to float on the surface of the knit.

These are an excellent choice for high-end garments, such as fine-gauge cashmere or delicate lace, where a traditional pin point could leave permanent holes or runs. The drawback is that they are best suited for flat, medium-weight fabrics; very heavy or bulky cabled sweaters may weaken the magnetic hold.

Always check the strength of the magnets before finalizing a design. A brooch that slides down a sleeve is more than a nuisance; it is a sign that the magnet isn’t strong enough for the weight of the felted wool.

Kilt and Scarf Style Pins: For Larger Brooches

Kilt pins are essentially oversized safety pins, often featuring a decorative loop that allows for a larger, more artistic statement. They are the go-to for substantial, heavy brooches that need extra structural support.

Because of their significant length, they are ideal for securing dense pieces of felt that would otherwise rotate or spin on a shorter pin. They also provide a rustic, artisan aesthetic that complements the organic nature of felted wool.

When using these, ensure the pin is inserted through a structural part of the garment, such as a collar seam or a button band. The weight of a large brooch can stretch out lighter fabric if it is simply pinned into the middle of a stockinette stitch section.

Clutch-Back Tie Tacks: For Small, Dainty Designs

Tie tacks are perfect for miniature felted sculptures, such as small floral brooches or decorative embellishments. They feature a short, needle-like post that is secured with a small metal or rubber clutch.

The precision of a tie tack allows it to sit perfectly centered on small designs without obstructing the view. However, because they rely on a single point of contact, they can occasionally rotate if the brooch is not perfectly balanced.

Consider adding a small stabilizer on the back of the felt before attaching the post. This prevents the tack from “wobbling” and ensures the piece stays oriented exactly as intended.

How to Choose the Right Pin Back for Your Project

Selecting the correct fastener begins with an honest assessment of the brooch’s weight and the fabric it will inhabit. A heavy, dense needle-felted piece requires the mechanical security of a sew-on bar, while a delicate, airy design is better served by a lightweight adhesive back.

Always consider the “swing” factor. If a brooch is long or asymmetrical, a two-point attachment—such as a long bar or a wide sew-on plate—is mandatory to keep the piece from tilting.

• For heavy brooches: Use long, multi-hole sew-on plates.
• For delicate lace: Use magnetic backs or the finest-gauge pin available.
• For everyday wear: A sturdy safety-catch bar pin remains the gold standard.

Sewing vs. Gluing: Attaching Your Brooch Back

The debate between sewing and gluing often boils down to a choice between permanence and speed. Sewing is almost always the more reliable method when working with felt, as the fibers offer a secure, dense base for the thread to grip.

If glue is the chosen route, avoid hot glue at all costs. It often lacks the necessary shear strength to hold a metal pin to a porous, flexible material like felt, eventually leading to the brooch popping off when exposed to temperature changes.

Opt instead for a high-quality two-part epoxy or an E6000-style industrial adhesive. These products maintain a slight flexibility when cured, preventing the bond from becoming brittle and snapping off the back of the felted wool.

Reinforcing Felt for a Durable, Long-Lasting Pin

Felt can sometimes be soft and yielding, which creates a challenge for rigid metal hardware. To combat this, add a stiffening layer to the back of the brooch before attaching the pin back.

A small circle of stiffened craft felt, leather, or even a piece of scrap fabric fused with heavy iron-on interfacing creates a solid foundation. This prevents the metal pin from tearing through the felted structure over time.

This reinforcement also hides the raw edges or the messy thread ends of a sew-on pin. It provides a polished, professional finish that makes the back of the brooch look just as clean as the front.

Brooch Pin Metals and Finishes: A Quick Guide

Metal finishes are not just about aesthetics; they affect how the pin interacts with your knitting and your skin. Nickel-plated pins are common, but they can be a source of irritation for those with skin sensitivities.

If the brooch will be worn against the skin, prioritize brass, copper, or stainless steel options. These metals are generally more hypoallergenic and durable than cheaper, plated alternatives that may tarnish or flake over time.

Match the metal tone to the character of the project to elevate the overall design. A darkened, antique bronze pin adds a rustic charm to earthy wools, while a bright, polished silver finish can make vibrant, dyed fibers pop with modern contrast.

Ultimately, the best pin back is one that disappears into the design, allowing the artistry of the felt to take center stage. By balancing weight, security, and attachment method, every brooch created can transition from a craft project into a reliable, wearable piece of jewelry. Remember that a bit of extra time spent reinforcing the back and choosing the correct hardware today will ensure the piece remains a cherished accessory for many years to come.
