In the world of quilting, 'Pre-cuts' are a game-changer. They allow you to skip hours of tedious cutting and jump straight into the creative part: sewing! But with delicious names like Jelly Rolls, Layer Cakes, and Charm Packs, how do you know which one is the 'secret ingredient' for your specific quilt?
At TextileCloth, we believe that the right quilting material should make your hobby easier, not more confusing. Here is our expert breakdown of the most popular pre-cut fabrics.
Jelly Roll Material
1. What is Jelly Roll Material?
A Jelly Roll is a bundle of fabric strips, typically 2.5 inches wide by 42–44 inches long (the full width of the fabric).
-
The Specs: Usually contains 40 strips per roll.
-
Best For: Strip quilting, 'Log Cabin' blocks, and the famous 'Jelly Roll Race' quilt.
-
Why use it? If your project involves a lot of borders or linear designs, jelly roll material is your best friend. It’s perfect for adding contrast and 'framing' other blocks.
Layer Cake Fabric
2. What is Layer Cake Fabric?
Despite the name, there’s no baking involved! Layer Cakes are stacks of 10' x 10' squares.
-
The Specs: Usually includes 42 squares per pack.
-
Best For: Large block quilts, 'Half-Square Triangles' (HSTs), and showcasing large-scale prints.
-
Why use it? Because layer cake fabric is a larger square, it offers more versatility than a Jelly Roll. You can cut a Layer Cake into smaller squares or even into 2.5-inch strips if you change your mind mid-project!
charm packs fabric
3. The Power of Charm Packs
Think of Charm Packs as the snack-sized version of pre-cuts. They are 5' x 5' squares.
-
The Specs: Usually 42 squares per pack.
-
Best For: Baby quilts, table runners, and simple quilt patterns for beginners.
-
Why use it? Charm packs are incredibly affordable. They are a great way to get a piece of every single fabric in a designer’s collection without spending a fortune.

How to Choose the Right One for Your Project?
Choose a Jelly Roll if...
You want to make a quilt with a lot of movement and lines. If you are following jelly roll quilt patterns, using the pre-cut jelly roll material ensures all your strips are perfectly uniform—something that is hard to achieve with manual cutting!
Choose a Layer Cake if...
You want to see the 'big picture.' If the quilting fabric you love has a large floral or geometric print, a 10-inch square will show off that design much better than a skinny strip or a tiny charm square.
Choose a Charm Pack if...
You are practicing your first 9 patch quilt pattern. Charm packs are the perfect size for these classic blocks. They are also ideal if you are on a budget but still want high-quality quilt and fabric collections.
⚠️ Pro Tip for Using Pre-cuts
Don't Pre-wash! Unlike buying fabric by the yard, you should never pre-wash Jelly Rolls, Layer Cakes, or Charm Packs. Because they are pre-cut, washing them will cause the edges to fray and ruin the precise dimensions. Simply sew your quilt and then wash the finished product for that beautiful, 'crinkled' vintage look.
