Good morning, quilters! Corey here.
Bookmark this guide before starting your next project.
Every quilter has stood in front of a wall of fabric asking the same question: which one does my project actually want? Today I'm putting the answer in one place—a fabric match guide by project, the numbers worth memorizing, and the prewash question, settled. Save it, print it, tape it to the sewing room wall.
The Fabric Match Guide
Traditional quilts → 100% quilting cotton. Stable, presses crisply, and pieces with precision—which is exactly why it's the default. Batiks count too: their tight weave means minimal fraying and rich, saturated color.
Baby quilts → quilting cotton or flannel on top, and if you want the "never puts it down" effect, back it with Cuddle® minky. Everything should be machine washable—baby quilts live hard lives.
Quilted bags → quilting cotton with structure added. The fabric supplies the personality; fusible interfacing or a stabilizer supplies the body. Skip loose weaves that stretch out of shape at stress points.
Home décor → sturdier cottons and panels. Table runners and wall hangings are the perfect place for a striking print you couldn't cut into small pieces.
Cozy throws → minky, full stop. It's a stretchy knit, so use a walking foot, a longer stitch, and plenty of clips—the payoff is a blanket nobody in the house will surrender.
Quilt backs → 108" widebacks. One seamless piece of backing, zero piecing. There's wideback flannel and batik widebacks too, so the back can match the personality of the front.
The numbers to memorize
- Standard quilting cotton is 42–44" wide. Pattern yardage requirements assume roughly 40" of usable width after selvages.
- Widebacks are 108" wide. Three yards typically backs a queen with room to spare.
- Fat quarter = 18" × 22". Same square inches as a regular quarter yard, but in a wider, far more usable shape. Browse individual fat quarters when you need just a taste of a print.
- Jelly roll strips = 2½" × width of fabric. Forty coordinated strips, no cutting required—see our jelly rolls.
- Precuts save the math entirely. Charm packs (5" squares), layer cakes (10" squares), and kits arrive already coordinated.
To prewash or not?
The honest answer: be consistent. Prewashing removes excess dye and shrinkage before it can pucker a finished quilt; skipping it keeps that crisp hand and gives a finished quilt the soft "crinkle" after its first wash. What causes trouble is mixing washed and unwashed fabrics in the same top. Deep reds and saturated batiks are the exception—test those for bleeding either way, and keep a color catcher handy.
Quick quality checks at the shelf
- Hold it up to the light. A quality quilting cotton has a tight, even weave with no thin patches.
- Check the grain. The print should run true to the weave—wildly off-grain prints fight you at every seam.
- Do the stretch test. Barely moves crossgrain? Woven, quilt away. Springs back? It's a knit—handle accordingly (see my Knit vs. Woven guide).
Remember
Matching the fabric to the project is 90% of the battle—the right fabric makes every step downstream easier, from cutting to quilting to washing. Keep this cheat sheet close, and when in doubt, start with quality quilting cotton: it's never the wrong answer.
Happy Quilting!
