Robert Kaufman Fabrics and Quilter's Paradise have joined forces to bring you a collection of eight essential quilting calculators. With these calculators you'll be able to quickly convert between yards and inches, meters and centimeters; learn how much fabric you need for backing, batting and borders; and determine how many rectangular pieces can be cut from a larger piece. There are even calculators for square-in-a-square, set-in and corner triangles. Here's a brief description of each calculator: Fabric Measurement Converter: Converts between inches and yards in decimal form, and yards in fractional form. (With metric equivalents.) Backing and Batting Calculator: Determines how much material from a bolt of fabric is needed to make the backing for a quilt. Piece Count Calculator: Shows the number of fixed-sized pieces of fabric that can be cut from a larger piece. Pieces to Area Calculator: Indicates how much fabric is needed in order to cut a given number of fixed-sized pieces. Binding Calculator: Tells you the amount of fabric required to bind your quilt, based on the quilt’s dimensions and the binding strip width. Border Calculator: Shows the amount of fabric required to create borders, based on a quilt’s dimensions and the width of the borders. Square-in-a-Square Calculator: Works out the key dimensions of a square-in-a-square block. Set-in and Corner Triangle Calculator: Determines the size of the square piece you’ll need to cut in order to create both unfinished set-in triangles and unfinished corner triangles.
