I agree with QuiltE and thought it might be the link she posted. Here's another you may be able to get patterns from

I did up some pics for fun that will help, I hope.
Sew fabric in strips ( I show ten 1 1/2" strips). From this you can cut 10 1/2" squares and cut once on the diagonal, then sew the sections A1 & A2 together along the diagonal side.
