  3. Before I’d start cutting large pieces of fabrics I would just do a small test with some fabric I don’t like much. To see how accurate the formula is. Then just calculate how many HST you want and do the math. Let’s assume 6 3/8 is correct. In a 42″ wide piece of fabric you Can fit a bit over 6 HST across. Now calculate how many you want to make and multiply by how many rows. For instance you want 40 HST. You’ll need 7 rows (6 x 7 = 42). Calculate how long your piece will be: 7 multiplied by 6 3/8 is a bit over 44 so your piece will be 44 x 42. Again test with a small batch first. And if the HSTs are too big they can always be trimmed to size. I hope this makes sense.
