Colors can easily be adjusted to your preference. Yarn requirements will vary depending on yarn type and your personal crochet style. To figure out how much yarn you will need I recommend the following technique: 1. Using the type of yarn you would like to complete the project with, crochet one square 2. Grab the yarn from the beginning of the square and the end and holding onto each point, undo the square. Measure the distance between your fingers. 3. Using the following calculation to estimate needed yarn in yards [Number of inches measures in test square] x [## of Color A Squares] = [total number of inches needed] [Total number of inches] / 36 = [Total number of yards] For example: Using weight 4 yarn I measured 22 inches between the distance of my fingers This pattern has 9281 green squares and 2719 white squares Green Yards Estimate: 22 x 9281 = 204,182 inches 204,182 / 36 = 5671 yards White Yards Estimate: 22 x 2719 = 59,828 inches 59,828 / 36 = 1662 yards
