This fabric is sold by the linear yard, either as a prepackaged quantity or by continuous yardage.
This fabric is available in pre-cut lengths that measure one yard (#3100-A, roll), three yards (#3100-B, roll), and five yards (#3100-C, roll). Each is packaged and sold separately. For your convenience, these "prepacks" can be purchased in any combination. However, if the length for any one fabric totals 10 yards or more, we suggest you purchase it in continuous, "cut to length" yardage.
Continuous, "Cut to Length" Yardage
If you know in advance that you intend to purchase 10 yards or more of any one fabric, it should be ordered in continuous, "cut to length" yardage. In this case, fabric will be cut once according to the total yardage ordered, and customers receive a price-per-yard discount as compared to prepacks.
Quantity discounts continue to deepen as the yardage increases for any one cut of one fabric.
