Quilting Precuts Explained
Precuts are coordinated bundles of fabric cut to a fixed size, sold as a full fabric collection in one package. They save cutting time and guarantee a matching color story, which makes them perfect for beginners and fast weekend quilts.
The Common Precut Types
Each precut has a standard shape and piece count. Knowing what is inside helps you pick the right bundle for your pattern.
| Precut | Shape | Pieces | Great for |
|---|---|---|---|
| Jelly roll | 2.5" × WOF strip | ~40 | Strip quilts, binding |
| Layer cake | 10" square | ~42 | Big-block quilts |
| Charm pack | 5" square | ~42 | Baby quilts, patchwork |
| Fat quarter bundle | 18×22" | 20–42 | Scrappy patchwork |
| Honey bun | 1.5" × WOF strip | ~40 | Applique, narrow strips |
What Each Precut Makes
A charm pack (42 five-inch squares) can become a small baby quilt top with just connecting strips. A jelly roll can become a whole strip quilt with no additional cutting, and a layer cake can be turned into 10-inch block quilts or subcut into smaller shapes.
Prewashing Precuts
Precuts are usually not prewashed because washing frays the small pieces. If you want to prewash, do it as a whole bundle inside a mesh bag, or plan for a little shrinkage in the finished quilt.
