I have found the easiest way to make HST is Bonnie Hunter's method with the Easy Angle ruler. Just 1/2" to the finished size you want and cut strips of the two colors. Stack right sides together and using the Easy Angle ruler, cut triangles. They are already stacked and ready to sew. Then there is no bias on the outside edges. If they need squared up, use Eleanor Burns triangle square ruler. Easy peesy! And I have my charm squares ready to make that hunter's star quilt the Jenny Doan way - love that quilt!!
