Pre-Washing Fabric or Not?
Do you pre-wash before cutting fabric?
For years I often skipped pre-washing fabric before making quilt blocks. Many quilters do, and there is nothing wrong with that approach. But over time I’m finding more situations where pre-washing is helpful before cutting, especially when using fabrics from different sources.
Why pre-wash fabric?
Pre-washing can help:
• Remove excess dye that could bleed into lighter fabrics later
• Shrink the fabric before cutting, rather than after the quilt is finished
• Remove some of the chemicals and finishes used during manufacturing
• Give a more accurate idea of how the fabric will look and feel after laundering
Not every quilter pre-washes. Some prefer the crisp feel that unwashed fabric has, and they like the slightly crinkled appearance quilts develop after their first wash. There is no single right way—choose the method that works best for your quilting style.
Quick steps for pre-washing fabric
Separate fabrics by color, especially dark reds, blues, and other strong colors.
Cut away loose threads along the raw edges. This helps reduce tangling and fraying during washing.
Place fabric in the washer using a mild detergent. Wash it the same way you expect the finished quilt to be washed.
Dry the fabric according to your preference. Some quilters use a dryer; others air dry.
Press the fabric with an iron to remove wrinkles and restore a smooth surface for cutting. Additionally, you may want to starch the fabric at this point.
Once pressed, your fabric is ready for measuring and cutting quilt blocks.
A helpful tip
· If you decide to pre-wash, try to be consistent within the same quilt project. Mixing heavily pre-shrunk fabric with unwashed fabric can sometimes lead to uneven shrinking later.
· One small quilting note: if you work with precuts like charm packs or jelly rolls, many quilters avoid pre-washing those because the smaller pieces can fray heavily or distort.
