Both fabric content & stretch factor play an important role in this. You may have come across this term whilst conducting your own research for a project, with many experts recommending ‘high or low percentage’ stretching. If after all of this you are still wondering, ‘what is a stretch factor?’, it refers to how far one can stretch a particular piece of fabric past its state of relaxation. This plays an important role in how the finished garment will sit on the body.
Each fabric will have its own stretch factor, as does their lycra, spandex or elastane content. Unless you are intimately familiar with the numerous options available, it can be difficult understanding what is the right stretching factor for your designs. To help, the team at Pattern Emporium have put together a quick fabric stretch guide below to help you choose the ideal fabric for you.
In the handmade world, stretch knit fabric is generally described as either 2-way or 4-way stretch.
NOTE: You will sometimes find fabrics that have a reasonable amount of vertical stretch (give/slight stretch), despite being described as a 2 way stretch. Do a stretch factor test (outlined below) if you can and if buying online, ask the seller if there is any vertical give.
Stretch factor is how far a fabric stretches past it’s relaxed state. This is important for the correct fit of a stretch fitted garment.
If you are sewing a fitted stretch garment it's important for the fabric to have both horizontal & vertical stretch.
As a fabric stretches OUT on your body, it will also pull UP.
For this reason, it's important for a fitted stretch garment to be made out of 4-way stretch.
If a fabric has no vertical stretch, the fabric won't be able to comfortably pull up, making it too short both through the body, crotch, armhole &/or legs. This can be very uncomfortable.
Skilled designers will begin by determining fabric stretch, allowing them to make the right decision when opting for those with a higher stretch percentage to create looser-fitting pieces or lower stretch percentages for a tighter fit. Learning how to measure yourself is crucial to minimising the issues with your garments throughout the process.
While many of us may start out tugging at the various fabrics in our collection – risking damage to its quality – determining stretch fabric can actually be super easy. Here's how:
1. PRINT OUT THE STRETCH FACTOR GUIDE:
2. CUT AND LABEL A FABRIC SWATCH:
3. DETERMINE HORIZONTAL STRETCH
4. VERTICAL STRETCH
Once you understand the ins and outs of fabric stretching factors, it becomes far easier to gain the necessary insight into how you will be able to manipulate your chosen material when fitting to garments. To make it even easier, simply refer to the fabric pages of your Pattern Emporium pattern. It will tell you exactly what stretch fabric you need.
