Fabric Bases 101 – How to Choose the Best Fabric

 

Picture this. You’ve found the perfect fabric for a new dress. Anticipation mounts as you receive the package in the mail and sit down to sew it. But, after spending hours on it, it doesn’t fit or feel like you imagined!

Sound familiar? Choosing fabric online can be difficult because you can’t physically feel or stretch it. We want to make buying fabric online as seamless and easy as possible. We’ve compiled all of the fabric bases as well as how they feel and stretch. You can end up with a beautiful dress that you feel good in!

 

What Makes the Fabric Bases Different?

We all know how cotton and polyester feel. But what about 95% Polyester/5% Spandex which is a very common content ratio? Not all fabrics act the same! There are many factors that play a part in how a fabric base feels and acts.

  1. Whether it’s woven or knitted
  2. How tightly its woven or knitted
  3. How heavy the fabric is (its GSM)
  4. The thread content of the fabric (polyester, cotton, spandex, etc.)

This can feel confusing if you aren’t familiar with these terms. Don’t worry, I’ll give you an overview! We are not always able to get the exact content percentages and gsm so I’ll include a description of the fabric without the technical terms so you can envision how it will feel and act in real life. Feel free to skip over the technicalities and straight to the descriptions and pictures of each fabric type!

What is GSM?

GSM stands for grams per square meter, which refers to the weight of a fabric. In general, the higher a fabric’s GSM, the thicker it’s likely to be.

Though fabric weights appear straightforward (a heavy fabric will result in a more structured garment, etc.), there are some caveats to consider.

For example, many knit fabrics have some spandex content, which adds extra weight but doesn’t make a knit feel or act heavier. Therefore, a knit that weighs 200 gsm can feel more lightweight than a woven fabric with the same weight. Therefore, fabrics with different fibers or weaves with the same weight may not have the exact same thickness. GSM is generally most helpful when comparing woven fabrics.

In general, it can be difficult to get an accurate idea of knits even when you know the weight because of how they are made. Knitting uses more fiber or threads than weaving. A knitted piece of cloth will weigh more than a woven piece that is the same size and content.

You may be new to using GSM as a fabric weight measurement and there are a few fabric types that we don’t have the GSM, so we also include our own assessment of whether the fabric is light, medium, or heavy weight. As a reference, the GSM of jeans is usually 340-450.

Woven Fabrics Vs. Knitted Fabrics

Whether the material is knitted or woven makes a big difference on the stretch and give of a fabric.

Here’s a diagram of the difference between woven materials and knit materials. Because of the way knit fabric is made, it will have a slight give even if it is 100% polyester. The looping design of knit fabrics can allow even non-stretchy threads (like polyester) to condense and straighten out when pulled, which lengthens the fabric in the given direction.

 Additionally, the tightness of the knit will affect the thread’s ability to straighten out and will thus affect the amount of stretch. Knit fabrics can also have different ways of arranging the loops together to form different textures or looks to the fabric.

Woven fabrics are also more likely to fray while knit material will not fray and does not need to be serged.

Tips on choosing the best fabric for a dress

If you love a lightweight fabric like rib knit or DBP, but don’t want the possibility of underwear lines, get a darker color! Dark colors hid so many flaws. Sewing mistakes and possible lines alike! On the other hand, if the fabric base isn’t color fast (like Liverpool) a lighter color will be best. You won’t run the risk of white shining through. Also take into account the size of the dress you are making. A lightweight knit like Double Brushed Poly will look much cuter as a size 6 dress then a size 18.

Selvage

Sometimes fabric has a wide white selvage which might look concerning. We understand! You don’t want to pay for unusable fabric! Good news! No matter how wide the selvage is, there is still 58”-60” inches of usable, printed fabric!
