When + How to Wash Quilting Fabric

Some quilters like to wash all of their fabric before cutting it, other quilters prefer to use unwashed fabric. While there are definitely pros and cons to prewashing fabric, there are times when all quilters should wash their fabric. It’s important to know when you really must wash and, when those times arise, how to wash quilting fabric to avoid ruining it.

Tips for washing quilting fabric

You should wash your quilting fabric if:

You plan to dye the fabric

Most fabric dyes work best on fabric that has been washed to remove any chemicals left in the manufacturing process. Check the dying instructions on your fabric dye to see if you should pre-wash your fabric.

The quilt will be given to a baby or child

Quilts given to a baby or child should be washed either before the fabric is cut, or after the quilt has been bound. This removes any chemicals or other residue from manufacturing that might irritate the sensitive skin of a baby or child

You have allergies

If you have skin allergies and find that you are sensitive to dyes in fabrics, you might want to wash the fabric before cutting to reduce or eliminate any reactions.

You are concerned about shrink or bleed

If you plan to wash the quilt after it is completed, you may want to wash the fabric beforehand. Washing the fabric before cutting it will reduce the amount of shrink and wrinkles in the finished quilt when washed. However, some people like the vintage look that comes from washing a quilt pieced from unwashed fabric.

When using fabrics with high contrast (especially red and white combinations), washing your fabrics before stitching will reduce the color from later bleeding onto the light fabrics during washing or storing the quilt.

You are using materials that require pre-washing fabrics

Some materials, such as some fusibles used in appliqué, require prewashing the quilting fabrics before using the fusibles. Read the package instructions on any materials you use in your quilts.

You are making a garment

Every now and then, quilters make clothes instead of quilts. Prewashing fabrics before making a garment will take out the shrink, ensuring that the garment you make stays the size you stitched it. If you plan on sewing a garment, read this article on washing fabric for garment sewing.

Got the need for clean? Here’s how to successfully wash quilting fabric:

1. Before washing your quilting fabrics, you must prepare any raw edges. The raw edges will fray in the wash. If you don’t prepare the edges before washing, the frayed threads can wrap around the fabric and washing machine, creating a tangled mess.

Here you can see the fraying results from different ways of preparing fabric:

prepped washed fabric

The easiest way to prepare fabric for washing is to use pinking shears. Cut along the raw edge of the fabric using pinking shears. Do not cut off the selvedge. You can do this very easily with a pinking blade on your rotary cutter.

Fringing the edges of the fabric creates less fraying in the wash than pinking shears, and is easy to do. Use shears to cut 3/4″ slits along the raw edge of the fabric, with each cut about 1/2″ apart. If you fold your fabric so that the two raw edges meet, you can cut both sides at once.

2. Once your fabric has been prepared, you can wash it in the washing machine. Use a gentle detergent that has no dyes or perfumes. Soak Wash makes a fabric wash specifically designed for quilting fabrics. If your washer has a second rinse cycle, take advantage of it to rinse out any extra residue.

3. After washing, you can dry your fabric in the dryer on the cotton or “permanent press” setting. Once the fabric has dried, prepare your fabric for cutting by ironing the fabric with starch or Best Press.

Some quick tips before you start washing your fabric:

  • Buy 5-10% extra fabric if you plan to prewash. Your fabric will shrink in the wash, and nothing is worse than cutting into your fabric only to find that you don’t have enough!
  • Flannels shrink more than quilting cottons, and high quality quilt cottons shrink less than cheap cottons.
  • If you expect your fabric to bleed in the wash, add several color catchers to absorb the dye. These can be purchased in the laundry aisle of your grocery store.
  • Don’t wash pre-cuts before sewing — they will shrink, and no longer be square or the right size for most pre-cut patterns.
  • When making a quilt, all the fabrics should either be washed or unwashed. Don’t mix washed fabrics with unwashed fabrics.
  • Wash like colored fabrics together: reds with reds, blues with blues, whites with whites, etc. to keep colors bright and prevent any bleed.

 Alright pro prewashers, any tips? And for those of you against prewashing, did we convince to consider prewashing at least sometimes?

When I wash the fabric I also add white vinegar and color catchers

I use my serger to serge the 2 raw edges together on a large piece of fabric. This makes your fabric a loop like a scarf…..then wash the piece even if it is a 1/2 yard or several yards.

Great job and I’m with you, except for the fringing part but I think there will be no end to this debate. I wash. The factory sizing gives me a rash. Washing is easier than medication. I’ve been at this 25 yrs, but maybe I can help the process along. The larger the pieces of yardage, the less the fraying. I use a short wash cycle. The fabric isn’t dirty; you are just removing the sizing. I wash with a teaspoon of Orvus for about 15 yds.; dry on regular, generally hotter than permanent press. If it’s going to shrink, do it now. If you want to wash small cuts, place them in a mesh lingerie bag. Minimum fraying but the sizing does get out. I only separate darks from lights. If they are going into the same quilt, they will be washed together. If you have a load of reds and one bleeds, how can you tell which one it is? Most reds, if left sitting wet, will bleed. Color catchers do work, if you can find them. Woolite will take the color out of cotton. I have a friend who washes no fabric if it is from before 1930; she doesn’t trust it. Many older fabrics will shred in a wash. I could go on for pages. Sorry.

I place my fabric in lingerie washing bags. I sort by color. I have various sized bags suitable for say fat 1/4rs right up to several meters. I have not had fraying of edges with this method. cheers

I never wash fabrics……except Batiks. Their high thread count and the wax used in production can make them very stiff and the wax may gunk up your needle
I was interested in the comment about washing jelly rolls etc. I have a lovely pattern for cuddly inside out chenille jelly roll quilt that depends on washing to get the effect. Would a pinked precut stop this?

If I only have a small amount to wash, such as a fat quarter or a few, I soak them in a dishwashing tub I keep just for that purpose, with warm water (not hot) and a small amount of detergent. Then I rinse well, squeeze most of the water out and press dry. The pressing takes care of any shrinking that might occur. If I’m making the quilt to be used, as opposed to being a keepsake only, I use regular detergent when I wash it. After all, whoever I give it to should be able to wash it with whatever they use normally. But I do enclose a note with each gift quilt about using cool water on a gentle cycle and about using a color catcher to keep their quilt colors bright.
