Directions: Check the % stretch of your knit as follows:
At the fabric store take the bolt of fabric and fold the knit fabric, parallel to and about 12 inches from the cur edge.
With thumbs and forefingers, grasp a 10-inch section of the knit at the folded edge. Stretch the knit as far as it will readily stretch. Measure that distance.
If the 10 inches of knit fabric – stretches to 12 ½ inches, the % stretch is 25%; 15inches is 50%; 17 1/2% inches is 75%; 20 inches is 100%
NOTE: Check all knit patterns carefully for the % stretch to use for that pattern. The size of the finished garment will decease or increase depending upon if the % stretch of the knit is less than or greater than indicated on the pattern, respectively. For example, you wear a size 10 shirt and the pattern calls for knit with 25% stretch. If you use a knit with 50% stretch, your skirt will be a size 12 because of the stretch of the fabric. For each 25% different from what the pattern recommends, our garment will be one size either larger or smaller than desired.
Determine the right side of the fabric.
Fold the fabric in half lengthwise, right sides together.
Pin the cut edges together every two inches.
Stitch along the cut edges with a ¼-inch seam allowance, stretching the fabric slightly while sewing.
Seam finish to keep single knits from running and to provide extra strength since the band will be stretched numerous times. Stitch both edges together 1/8 inch from the first stitching in the seam allowance.
