Fat Quarters, Jelly Rolls, Layer Cakes and Other Quilting Terms That Sound Like a Bakery Menu
Confused by quilting terms like fat quarters, jelly rolls, layer cakes, charm packs, and honey buns? Learn what quilting precuts are, how fabric collections work, and how to choose the right precut bundle for your next quilting project. A beginner-friendly guide to understanding quilting fabric bundles and panels.
One of the more confusing parts of learning to quilt is discovering that quilters apparently do their fabric shopping at a bakery.
Layer cakes.
Jelly rolls.
Honey buns.
Fat quarters.
Fat eighths.
For the longest time, I assumed somebody in the quilting industry got hungry during a marketing meeting and things just escalated from there.
As it turns out, these terms actually make sense once you understand what they are and why they exist.
So let's decode some quilting language.
First, What Is a Fabric Collection?
Before we talk about precuts, we need to talk about fabric collections, sometimes called fabric lines.
A fabric collection is a group of coordinating fabrics designed to work together.
Think of it as a family.
The designer creates multiple prints using the same color palette and theme.
You might have:
Large floral prints
Small floral prints
Geometric prints
Dots
Stripes
Tone-on-tone prints
Background fabrics
All designed to coordinate beautifully.
When you see a collection displayed in a quilt shop, that's why everything seems to match so effortlessly.
Someone already did the color planning for you.
Many collections also include:
Light fabrics
Medium-value fabrics
Dark fabrics
This balance helps quilters create contrast and visual interest in a quilt.
What Is a Fabric "Print"?
A print simply refers to an individual fabric design within the collection.
For example, a collection will often contain anywhere from 8-20 different prints, with most full-sized collections coming in with around 10-15 unique designs made into two or three different colorways.
This becomes important when we start talking about precuts.
Because many precuts contain one piece from every print in the collection.
What Is a Fat Quarter?
A fat quarter is probably the most common precut in quilting.
A regular quarter-yard of fabric is cut like this:
9" × 44"
While technically a quarter yard, it's long and skinny.
A fat quarter is cut differently:
Approximately 18" × 22"
Same amount of fabric.
Different shape.
Why does this matter?
Because an 18" × 22" piece is far more useful for quilting.
You can cut larger blocks, applique shapes, bag pieces, borders, and countless other project components from a fat quarter.
This is why quilters often buy fat quarters when they love a fabric but don't necessarily need a full yard.
Or two yards.
Or five yards.
Not that anyone would do that.
What Is a Fat Eighth?
A fat eighth is exactly what it sounds like.
It's half of a fat quarter.
Approximately:
9" × 22"
Many fabric collections are now available as fat eighth bundles.
These are wonderful when:
You want a lot of variety
You're making scrappy quilts
You don't need large pieces
You have limited storage space
Although if you're a quilter, "limited storage space" eventually becomes a relative term.
What Is a Layer Cake?
A layer cake consists of pre-cut squares.
Most commonly:
10" × 10"
A typical layer cake contains one or more squares from each print in a fabric collection.
Often around 42 squares.
The beauty of a layer cake is convenience.
No cutting.
No measuring.
No wondering if your square is actually square.
You simply open the package and start sewing.
Many quilt patterns are specifically designed around layer cakes.
What Is a Jelly Roll?
A jelly roll contains pre-cut strips (40-42).
Most commonly:
2½" × Width of Fabric
(Width of fabric is usually about 42-44 inches.)
Like layer cakes, jelly rolls often include one or more strips from every print in a collection.
Jelly rolls are popular because strips are incredibly versatile.
You can use them for:
Strip quilts
Log cabin blocks
Borders
Binding
Rail fence quilts
Bargello quilts
They're also a wonderful way to enjoy an entire collection without purchasing yards of every print.
What Is a Honey Bun?
A honey bun is essentially a narrower jelly roll.
The strips are:
1½" wide
Instead of 2½" wide.
has 40-42 stips per roll.
Honey buns are perfect for:
Small piecing
Borders
Table runners
Decorative projects
Mini quilts
They're less common than jelly rolls but incredibly useful for certain projects.
Other Common Precuts
You may also encounter:
Charm Packs
Contain 42 pre-cut squares that are:
5" × 5"
Like most precuts, charm packs typically contain one square from each print in a fabric collection.
Charm packs are incredibly popular because they're affordable, easy to store, and work beautifully for many quilt patterns.
They're often a beginner's first introduction to precuts because they offer a lot of variety without requiring a large investment.
Charm packs are commonly used for:
Baby quilts
Lap quilts
Table runners
Tote bags
Scrappy projects
Quilt blocks that feature many different fabrics
If you've ever admired a quilt that seems to contain dozens of coordinating fabrics, there's a good chance a charm pack was involved somewhere along the way.
Mini Charm Packs
Contain 42 tiny squares that measure 2½" × 2½"
They're essentially the quilting equivalent of snack-sized candy.
Small. Cute. Difficult to stop collecting.
Mini charms are wonderful for:
Doll quilts
Mug rugs
Small wall hangings
Decorative accents
Tiny patchwork projects
They can also be combined to create larger blocks and more complex designs.
Just know that the smaller the pieces become, the more important accuracy becomes.Some quilters absolutely love tiny piecing.Others discover very quickly that their happiness lives somewhere north of a 5-inch square.Both positions are completely reasonable.
Dessert Rolls
Typically twenty (20) 5" strips
Not as common but occasionally available.
Because apparently we hadn't exhausted the bakery theme yet.
Let's Talk About Panels
Many fabric collections also include a panel.
A panel is a large printed piece of fabric designed as a focal point.
Instead of repeating prints across the fabric, the panel contains specific images or scenes.
Examples include:
Christmas scenes
Farm animals
Children's themes
Wildlife
Patriotic designs
Vintage trucks
Seasonal artwork
Some panels contain a single large image.
Others contain multiple smaller blocks that can be cut apart.
Panels are fantastic for:
Baby quilts
Children's quilts
Wall hangings
Quick gifts
Table toppers
Pillows
Tote bags
They're also wonderful when you need a project finished before next Christmas rather than the Christmas three years from now.
Why Quilters Love Precuts
The biggest advantage is simple:
The work is already done.
The manufacturer has:
Coordinated the colors
Cut the pieces
Packaged the collection
This allows quilters to focus on designing and sewing.
Precuts are particularly helpful for beginners because they remove much of the stress involved in selecting coordinating fabrics.
You can purchase an entire collection in one bundle and know everything will work together.
My Advice for Beginners
If you're standing in a quilt shop looking completely overwhelmed, start with a precut bundle.
Pick a collection that makes you smile.
Don't overthink it.
A layer cake, jelly roll, charm pack, or fat quarter bundle is a wonderful way to learn color, fabric coordination, and quilt construction.
Before long, you'll find yourself saying things like:
"I only went in for one fat quarter."
And every experienced quilter within earshot will immediately know that's not how the story ended.
In future posts we'll dive deeper into how to choose fabrics that work well together, how to understand color value in quilts, and why some quilts seem to glow while others fall a little flat.
Spoiler alert: it's usually not the fabric's fault.
