The count of fabric you use is up to your personal preferences. The count will determine the final size of the design. You can determine the amount of fabric you want based on the count you choose by using a cross stitch calculator. There is a good one at this link: https://yarntree.com/java/xstitchcal.htm The count for this chart is 327 x 341 The fabric I sell is pre-packaged. You may need a larger piece for this chart than is contained in the packages.
