To Prewash or Not to Prewash? That is the Question.

Hi Friends! 

I get asked a lot about whether or not their new fabric should be washed before sewing with it.  The answer depends on multiple factors and often just to personal preferences, but I want to help demystify this a little bit! When it comes to prewashing organic cotton fabric before sewing, there are both pros and cons to consider. Here are some points to help you make an informed decision:

Pros of prewashing new fabric:

1. Shrinkage: Prewashing helps to remove any residual shrinkage in the fabric. Organic cotton, like any other fabric, may shrink when washed for the first time. By prewashing, you can prevent any unexpected shrinkage that could affect the fit of your finished garment or project.  This is important to consider if you are making something that needs very specific finished dimensions, such as apparel.  Usually, if you are sewing garments from woven materials, the pattern will require prewashing before any cutting of the fabric is done.  You can reduce the tattering of your new fabric by cutting the raw edges with pinking sheers before washing and drying.
2. Color bleeding: Prewashing allows you to identify any potential color bleeding issues. Some fabrics, especially those with vibrant or dark colors (hello red), may bleed when washed. By prewashing separately, you can address any bleeding before sewing your fabric into a finished item.
3. Softening: Prewashing your new fabric can help soften the fabric, making it more comfortable to wear or use. This is particularly beneficial if you're making clothing items that will be in direct contact with your skin.

Cons of prewashing new fabric:

1. Time-consuming: Prewashing can be a time-consuming process, especially if you have a large amount of fabric. It involves washing, drying, and potentially ironing the fabric before you can start sewing.
2. Fabric distortion: Certain fabrics can warp or distort after washing. This may affect the alignment of pattern pieces and make sewing more challenging. In such cases, you may need to reshape or iron the fabric back into its original shape before cutting and sewing.
3. Loss of finish: Some fabrics come with special finishes, such as a crisp or smooth texture, which may be lost or altered after washing. If maintaining the original finish is important for your project, prewashing might not be desirable.
4. Loss of quilting "crinkle": Are you a fan of crinkly quilts?  I sure am!  The way to achieve that signature cozy crinkle is to not prewash your materials.  Instead, you will want to wash and dry your handmade quilt after it is completely finished.  

When washing your fabrics (whether you choose to do that before or after the construction of your project), you will generally want to choose an eco-friendly detergent and wash with cold water and tumble dry low or even hang to dry.  This will help your handmade project last longer so it can be enjoyed for many decades!
