Pre-Cut Quilt Fabric Guide

Guide to Specialty Cuts

All you need to know about Fat Quarter Bundles, Charm Packs, Jelly Rolls and all the rest.

Many fabric manufacturers offer specialty cut items in conjunction with many of their collections. Specialty cuts, also called pre-cut items, are fabrics cut into specific sizes and typically packaged by collection. There are many different sizes of specialty cuts, and they are based on the most common cuts used by quilters. Besides regular yardage, which is sold by the yard, the most well-known specialty cuts include:

There are many others, and new ones pop up all the time. On top of that, different fabric manufacturers call their cuts different names, although some are the same size.

To help you understand these and find the one you need, we have described each specialty cut we offer below. Keep in mind that not all specialty cuts are available for all groups.

Please note, all of the fabric we sell is 100% cotton and 44" wide unless stated otherwise.
