Cut the number of strips indicated in each fabric in the HST.

​

In general, the strip piecing method uses less fabric than any traditional HST method.

​

If you bought the fabric listed in the fabric requirements for your pattern (assuming there was no error), you should have more than enough fabric.

Remember:

  • Unfinished size = finished size + 1/2" 

       This leaves room for the seam allowance.

  • Most yardage is 42" width of fabric

  • Most fat quarters are 21" width of fabric​​

  • 0.125 = 1/8

  • 0.25 = 1/4

  • ​0.375 = 3/8

  • 0.5 = 1/2

  • 0.625 = 5/8

  • 0.75 = 3/4

  • 0.875 = 7/8
