Take complementary fabrics and cut them into 10″ squares. Do the same for the background fabric. Do the easy 8 method to get 8 half-square triangles. Place a background square on top of a colored square. Draw a diagonal line from corner to corner in both directions. Sew 1/4″ away from both sides of the lines. Cut in the middle horizontally and vertically, then cut directly on the diagonal lines. Trim each into 4 1/2″ squares and press them open.
Take one charm square and cut it in half in both directions to get 4 squares. Cut 2 1/2″ squares from your background fabric. Make 2 of the colored squares into half-square triangles. Draw a diagonal line from corner to corner on 2 background squares and place them on top of the two colored squares. Sew directly on the line then trim excess. Press them open.
Sew them all together just like a four-patch. See the photo below for reference. You need 8 of this unit for each block. Sew them in pairs. Make sure they go in opposite directions (up then down) forming a crown.
Assemble the blocks just like in the photo below. Sew them all together to make the block.
