Precuts — fabrics offered in already-cut bundles of various shapes and sizes — provide an economical way to purchase small amounts of fabric. Precuts may be offered as an assortment of 21/2"-wide strips, 5" charm squares, and/or 10" squares. Two common specialty cuts — fat quarters and fat eighths — are found in a majority of fabric and quilt shops as well as online. You will find some projects on this website call for 18x22" pieces (fat quarters) and 9x22" pieces (fat eights) in materials lists.
A traditional 1/4-yard cut and a fat quarter contain the same amount of fabric but differ in shape. A traditional 1/4-yard cut measures 9x44". A fat quarter, on the other hand, is cut crosswise from a 1/2-yard piece of fabric (an 18x44" rectangle) to yield an 18x22" “fat” 1/4-yard piece.
A traditional 1/8-yard cut and a fat eighth contain the same amount of fabric but differ in shape. A traditional 1/8-yard cut is 4-1/2x44". A fat eighth, on the other hand, is cut crosswise from a 1/4-yard piece of fabric (a 9x44" rectangle) to yield a 9x22" “fat” 1/8-yard piece.
