#VERTICAL STRETCH HOW TO#

WHAT STRETCH FACTOR DO I NEED TO SEW PATTERN EMPORIUM PATTERNS?

Repeat Steps 3-5, this time folding the fabric in half along the vertical grain.

Note the % stretch factor it reaches on the guide.

Hold fabric at left edge (A) of guide & stretch as far right as possible.

Fold the fabric swatch in half, along the horizontal grain.

Draw an arrow on your fabric to remind you which direction horizontal is.

Don’t include the actual selvage in your sample.

Measure & cut a fabric sample 10cm x 10cm (3 7/8”), on the grain of the fabric.

You will be using this guide in the process, so make sure it's printed actual size.

Print out this simple fabric stretch factor guide first.

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.

#VERTICAL STRETCH HOW TO#

Learning how to measure yourself is crucial to minimising the issues with your garments throughout the process. 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. 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. If you are sewing a fitted stretch garment it's important for the fabric to have both horizontal & vertical stretch.Īs a fabric stretches OUT on your body, it will also pull UP.įor this reason, it's important for a fitted stretch garment to be made out of 4-way stretch. WHY IS DETERMINING STRETCH FACTOR IMPORTANT? This is important for the correct fit of a stretch fitted garment. Stretch factor is how far a fabric stretches past it’s relaxed state. Do a stretch factor test (outlined below) if you can and if buying online, ask the seller if there is any vertical give. 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. Not suitable for fitted stretch garments when the vertical stretch is zero (rigid).Fabric stretches selvage to selvage, horizontally across the fabric BUT NOT vertically up and down the fabric.Recommended for the waistband of the Heartlight & Starlight Skirts.Recommended for the Spellbound & Wanderlust Dresses, the True Romance, Allure & Trapeze Tops.Perfect for fitted or fit & flare stretch garments that need to stretch over our curves.Contains a % of lycra, spandex or elastane to give it that stretch & recovery.Generally recovers much better than a 2-way stretch.The fabric stretches both across the fabric AND up & down the fabric.In the handmade world, stretch knit fabric is generally described as either 2-way or 4-way stretch. 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. Unless you are intimately familiar with the numerous options available, it can be difficult understanding what is the right stretching factor for your designs. This plays an important role in how the finished garment will sit on the body.Įach fabric will have its own stretch factor, as does their lycra, spandex or elastane content. 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.

The equation for the following transformation of y = x a vertical stretch by a factor of 6 is given by y = 6x.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. Hence y = 6x vertically stretches the function. becomes closer to y axis.When x is divided by the function y spreads horizontally (moves away from the y axis). When x is multiplied by 6 the function y stretches vertically i.e. y = x/6 (function horizontally stretched).The above can be demonstrated with help of a diagram where three curves are plotted: In general a horizontal stretch is given by the equation y = cf(x) = f(cx) where 0 In general a vertical shrink is given by the equation y = bf(x) = f(bx) where b > 1.When either f(x) or x is multiplied by a number, functions can “stretch” or “shrink” vertically or horizontally, respectively when graphed.In vertical stretch transformation the following needs to be noted: Write an equation for the following transformation of y = x a vertical stretch by a factor of 6.
