Why Fabric Choice Matters
The fabric you choose affects everything: how the finished item looks, how it drapes, how durable it is, and how easy it is to sew. Choosing the wrong fabric for a pattern can lead to poor results even with perfect technique. Understanding the main fabric categories will help you make informed decisions for every project.
Woven vs. Knit Fabrics
This is the most fundamental distinction in fabric types:
- Woven fabrics are made from threads interlaced at right angles. They have little to no stretch (unless they contain elastane) and require seam finishing to prevent fraying. Most patterns for clothing, bags, and home décor call for woven fabric.
- Knit fabrics are made from interlocking loops of yarn. They stretch in at least one direction and are used for T-shirts, leggings, and activewear. They require a stretch stitch or overlocker to sew properly.
Common Fabric Types and Their Uses
| Fabric | Type | Best For | Sewing Difficulty |
|---|---|---|---|
| Cotton | Woven | Quilts, bags, beginner garments | Easy |
| Linen | Woven | Summer clothes, home décor | Easy–Moderate |
| Denim | Woven | Jeans, jackets, bags | Moderate (heavy) |
| Jersey (cotton knit) | Knit | T-shirts, casual dresses | Moderate |
| Chiffon | Woven | Blouses, overlays, scarves | Difficult (slippery) |
| Silk | Woven | Blouses, lingerie, linings | Difficult |
| Fleece | Knit | Blankets, casual wear | Easy |
| Canvas | Woven | Bags, upholstery, aprons | Easy (heavy) |
| Velvet | Woven/Knit | Evening wear, cushions | Difficult (pile) |
Understanding Fabric Grain
The grain of a fabric refers to the direction of the threads. The straight grain runs parallel to the selvedge (finished edge) and has the least stretch. The crossgrain runs perpendicular, with slight stretch. The bias grain runs at 45 degrees and has the most stretch — used for binding and draping effects.
Always cut pattern pieces on the grain specified unless the pattern says otherwise. Off-grain cutting causes garments to twist and hang unevenly.
Pre-Washing Your Fabric
Most natural fabrics — especially cotton and linen — shrink when washed. Always pre-wash and dry your fabric before cutting, using the same method you'll use to launder the finished item. Skipping this step can cause a completed garment to distort or shrink after its first wash.
Thread and Fabric Pairing
- Cotton fabric: Use cotton or polyester thread.
- Stretchy knits: Use polyester thread, which has slight elasticity.
- Delicate fabrics (silk, chiffon): Use fine silk or lightweight polyester thread.
- Heavy fabrics (canvas, denim): Use heavy-duty polyester or topstitching thread.
Tips for Buying Fabric
- Always check the fabric content label — natural fibres behave very differently from synthetics.
- Buy a little extra (10–15%) to account for pre-washing shrinkage and cutting mistakes.
- Hold the fabric up to drape it over your hand — this gives you a sense of how it will fall in a garment.
- Test stretch before assuming a fabric is woven or knit.
