Should I Wash Canvas Before Sewing

by

As I get ready to start a sewing project, especially with canvas material, a common question comes up – should the canvas be washed before sewing? To address this inquiry, we will examine the reasoning behind pre-washing fabric, specifically canvas, and its impact on the strength and appearance of the final result.

Understanding Canvas Fabric

Canvas is a sturdy, durable, and heavyweight fabric commonly used in making bags, tents, footwear, and other items that require a robust material. It is also popular in arts for painting because of its excellent texture and durability. However, when it comes to sewing, it’s essential to know how to prepare canvas fabric properly to ensure the longevity of your project.

To Pre-Wash or Not to Pre-Wash?

There is a divided opinion in the sewing community about whether it’s necessary to pre-wash fabric or not. However, in the case of canvas, it is generally recommended that you do pre-wash the fabric before sewing.

Why Pre-Wash Canvas?

There are three main reasons why you should consider pre-washing your canvas:

  1. Shrinkage: Like many other fabrics, canvas tends to shrink when it gets wet. If you sew an item with unwashed canvas and then wash the finished product, the canvas may shrink, distorting the shape of the item.
  2. Color Bleeding: Canvas, especially colored ones, can bleed color when washed. Pre-washing helps to eliminate excess dye, reducing the risk of color bleeding or fading in the future.
  3. Softening: Canvas is a relatively stiff fabric. Washing it before sewing can help soften the fabric, making it easier to work with.

How to Pre-Wash Canvas?

Pre-washing canvas is a straightforward process:

  1. Fill your washing machine or a large basin with warm water. Add a mild detergent.
  2. Submerge the canvas fabric in the water, ensuring that it’s fully saturated. Let it soak for about 30 minutes.
  3. Rinse the canvas thoroughly and gently squeeze out excess water. Do not wring as it can distort the fabric.
  4. Hang the fabric out to dry, or use the low setting on your dryer.

Once the fabric is dry, iron it to remove any wrinkles or creases before you start sewing.

Conclusion

In conclusion, it is generally recommended to pre-wash canvas before sewing. Doing so helps to reduce shrinkage and color bleeding, and makes the fabric easier to work with. However, always consider the nature of the project and the specific instructions given by the fabric manufacturer. When in doubt, it’s better to err on the side of caution and wash the fabric first.

Happy Sewing!
