You can go to the left and click on "cross stitch fabric". Then you will see a calculator. Enter the number of stitches for the pattern: 181w x 231h. Then click the arrow and decide what type of fabric you will use and the stitch count (36 count linen like the pattern suggests) or something else (16 count Aida, etc.).
Then you will see the size fabric to be used --be sure to add a couple extra inches on all 4 sides for the framing. If you don't get this then post again and I'll try. Just a stitcher who saw your post....

Hello,

Unfortunately, we do not carry the specific fabric that this design calls for so a fabric will not be listed in the supplies list to purchase. You can choose a different fabric from our selections on our Fabric Page on the website if you would like. Maubennett gave some really instructions on how to do that in the post above this one :) In our 36ct. Linen section the colors: Flax, Platinum or Cream would all be good substitutions.
