You can adjust the size of the bracelet band by increasing or reducing the number of rows on either end. To keep the design centered, add or subtract rows at both ends by the number generated by the following formula (round up or down if you get a fraction):
(15 x total number of inches to add or subtract) ÷ 2
Example: To make the band a half inch shorter, first multiply 15 and .5 for 7.75. Now divide 7.75 by 2 to get 3.875. Rounding up, you should reduce the pattern by about four rows on each end.
The pattern used for the bracelet in the photo was shortened to accommodate a smaller wrist.
