Fabric pre-cuts are a fantastic way to create a Patchwork quilt or other pieced project.  Fat quarter bundles are a great way to buy a small amount of each fabric from a collection and you know that, because the fabric is all from the same collection, it will always co-ordinate really well together to make your finished project look fabulous.  Jelly rolls, sometimes called design rolls, contain strips of fabric 2.5" wide, usually around 44" long (width of the fabric).  Charm packs contain 5" squares and layer cakes contain 10" squares.  These pre-cut cottons are perfect for quilters and crafters alike.
