side triangles are the teal along the edges and the corner triangles are orange.
for side setting triangles, you will cut the square across both diagonals.
for the corner triangles you cut 2 squares once across the diagonal (you'll only need 2 squares because a quilt only has four corners).
i recommend spraying the fabric with some sizing, best press, or starch before cutting to help stabilize the bias edges.
for those that are interested, here is the math formula for figuring out the square size. i round up to the nearest 1/8 inch.
for the side setting triangles:
multiply finished block by 1.414 and add 1.25
for the corner triangles:divide finished block by 1.414 and add .875
