Quilting Terms and Meanings: A Beginner’s Glossary

A quilting pattern can look like a different language at first. The good news is that most instructions rely on the same small group of words. Keep this glossary nearby while you read a pattern, shop for fabric, or plan your first quilt.

These are practical working definitions, not rules meant to make the craft feel fussy. Different teachers may use a word a little differently, so a pattern’s own directions always come first.

Fabric and cutting terms

Backing

The fabric on the back of a quilt. It can be one wide piece or several pieces joined together. Your backing calculator helps estimate how much you need after you choose a quilt size.

Bias

The stretchy diagonal direction of woven fabric, running at roughly 45 degrees across the grain. Bias binding is useful around curves because it bends more easily than straight-grain strips.

Fat quarter

A quarter-yard cut that has been cut once across the width and once along the length. It is shorter and wider than a regular quarter-yard cut, which makes it useful for small blocks and scrappy projects.

Fussy cut

To cut a specific part of a print so a flower, character, or motif lands exactly where you want it in a block. It uses more fabric, but the finished detail can be worth it.

Grain

The direction of threads in woven fabric. Lengthwise grain runs parallel to the selvages and has the least stretch. Crosswise grain runs from selvage to selvage. Knowing the grain helps blocks stay square.

Selvage

The tightly woven finished edge along both long sides of fabric. It often includes the maker’s name and color dots. Remove it from seam allowances because it can behave differently from the usable fabric.

WOF

Short for width of fabric, the measurement from one selvage edge to the other. A pattern may say “cut four strips WOF,” meaning four long strips across the fabric width.

Piecing and block terms

Block

A unit made from fabric pieces that becomes part of the quilt top. A quilt may repeat one block or combine many different blocks in a sampler.

Chain piecing

Sewing one pair of pieces after another without cutting the thread between them. The little thread chain saves time and keeps small units in order.

HST

Short for half-square triangle. It is a square made from two triangles, usually with a diagonal seam. HSTs appear in countless traditional and modern block designs.

Press, do not iron

Pressing means lifting and placing the iron to set a seam. Ironing back and forth can stretch bias edges and distort a block. Press seams to one side or open as your pattern directs.

RST

Short for right sides together. Place the printed or intended front sides of two fabrics facing each other before sewing a seam, then open the pieces to reveal the right sides.

Scant quarter-inch seam

A seam slightly narrower than ¼ inch. It gives a tiny bit of extra room inside a unit, which helps when seams and points need to meet cleanly.

Squaring up

Trimming a block or unit to its exact required size with a ruler and rotary cutter. Square up only after checking the pattern, since trimming too early can remove needed fabric.

Building the quilt

Batting

The middle layer that gives a quilt warmth, loft, and texture. Cotton, cotton blends, wool, and polyester batting behave differently, so read the label before choosing one for a project.

Basting

Temporarily holding the quilt layers together before quilting. Safety pins, spray adhesive, hand stitches, or long machine stitches can all work. The goal is to stop layers from shifting.

Quilt sandwich

The three layers assembled for quilting: quilt top, batting, and backing. Think of it as the point when your pieced top becomes ready to be finished.

Quilting

The stitches that secure all three layers. You can quilt by hand, on a domestic machine, or with a longarm machine. Dense quilting creates more texture, while wider spacing keeps more loft.

Stitch in the ditch

Quilting directly along a seam line where two fabrics meet. It is a subtle way to hold layers together while letting the patchwork remain the focus.

Walking foot

A sewing-machine foot that helps feed the top and bottom layers together. It is popular for straight-line quilting because it reduces shifting and puckers.

Finishing terms

Binding

The strip of fabric that wraps around a quilt’s raw outer edge. It protects the edge and gives the quilt a finished frame. Use the binding calculator to estimate how much fabric to cut.

Bearding

Batting fibers working through the quilt top or backing, creating a fuzzy appearance. A compatible batting and tightly woven fabric can help reduce it.

Label

A small piece of fabric on the back of the quilt that records the maker, date, recipient, or story. It is easy to skip in the moment and lovely to have years later.

UFO and WIP

UFO means unfinished object. WIP means work in progress. Both are friendly ways of describing a project that is waiting its turn, not a reason to feel guilty about your fabric stash.

Use the terms to shop with confidence

Once you know what a pattern is asking for, shopping becomes much simpler. If it calls for fat quarters, you know you need flexible cuts rather than one long piece. If it calls for backing WOF, you can compare regular fabric with wideback options before you buy.

Start with the pattern, write down the cuts and terms you do not recognize, then use this page to translate them. SewMe’s fabric collections, quilt kits, and calculators are here when you are ready to turn that plan into a project.

Frequently asked questions

What is the difference between piecing and quilting?

Piecing is sewing fabric pieces together to make the quilt top. Quilting is the stitching that holds the finished top, batting, and backing together. Many people use “quilting” for the whole hobby, but patterns often use the words more precisely.

What does WOF mean in quilting?

WOF means width of fabric. It is the distance from selvage to selvage, and it is commonly used when a pattern tells you how to cut strips. Check the usable width of your fabric before cutting, especially when a pattern is exact.

What does a scant quarter-inch seam mean?

It is a seam that is just a thread or two narrower than a full quarter inch. It leaves a little more fabric in the finished unit, which can help pieces fit accurately when they are joined.

What is the easiest quilting term to learn first?

Start with the quilt sandwich, seam allowance, right sides together, and width of fabric. Those four ideas appear in many beginner patterns and make the rest of the instructions much easier to follow.
