Any pattern can be converted to be stitched on a different fabric count than it calls for, it just changes the size of the completed piece.
Use our online fabric calculator to help you figure out the size of fabric you will need depending on the stitch count of your pattern. Just for your reference here is the math behind it...
Let's say you have a pattern that is 84 stitches X 84 stitches. To figure out the fabric size needed, you divide the number of stitches by the stitch count. So...
84 ÷ 14 = 6" (final piece will be 6" x 6")
84 ÷ 16 = 5.25" (final piece will be 5.25" x 5.25")
84 ÷ 18 = 4.66" (final piece will be 4.66" x 4.66")
84 ÷ 20 = 4.2" (final piece will be 4.2" x 4.2")
As you can see, the higher the stitch count, the smaller your finished piece will be.
