Compare picot edge, knitted, and woven elastic to choose the right type for your sewing project. Learn key differences, best uses, and decision rules.
Quick Answer
Choose knitted elastic for soft, comfortable waistbands and everyday garments; choose picot edge elastic for decorative trims and lightweight projects; choose woven elastic for heavy-duty applications that need to stay flat under stress.
Why Elastic Type Matters
Elastic isn't one-size-fits-all. The construction—knitted, woven, or braided—affects how it stretches, recovers, and lies flat in your project. Choosing the wrong type can lead to twisting, discomfort, or a finish that looks unprofessional. This guide breaks down the main types so you can match the elastic to your fabric and use.
Woven elastic has a firm, non-rolling feel and is often used in waistbands and heavy fabrics. Knitted elastic is softer and more comfortable against the skin, making it a favorite for loungewear and children's clothing. Picot edge elastic adds a decorative scalloped edge, perfect for visible trims and lightweight finishes.
Key Differences at a Glance
Knitted elastic stretches and recovers gently, which makes it ideal for garments where comfort is key. It's also less likely to roll, especially in wider widths. Woven elastic is stronger and holds its shape well, but it can be less comfortable for direct skin contact. Picot edge elastic is both functional and decorative, but it's usually narrower and more delicate, so it's not meant for heavy loads.
The width you choose also matters. Narrower elastics (like 12 mm) work well for lightweight fabrics and casings, while wider elastics (like 75 mm) provide more support and are often used in waistbands without a casing. Think about the weight of your fabric and how much stretch you need before you buy.
Decision Rules for Choosing Elastic
- For soft, comfortable waistbands: Choose knitted elastic in a width that matches your fabric weight. A 12 mm or 31 mm width works well for most garments. It stretches gently and lies flat, reducing bulk. Test the elastic on a scrap of fabric to confirm the stretch feels right.
- For decorative visible trims: Use picot edge elastic like the 13 mm dark gray option. Its scalloped edge adds charm to sleeves, necklines, or craft projects. It's not meant for heavy loads. Keep a small piece of picot elastic in your notions box for quick embellishments.
- For heavy-duty or wide support: Select a wide knitted elastic, such as the 75 mm version, for waistbands that need to hold their shape without rolling. It's also great for costumes and crafts. When using wide elastic, sew it directly to the fabric or use a casing that accommodates its width.
- For projects needing firm, non-rolling hold: If your fabric is heavy or you need elastic that won't stretch out, consider woven elastic. It's stiffer and less comfortable against the skin, so use it in casings or under layers. Woven elastic is not ideal for direct skin contact—pair it with a fabric covering.
