Diamond in a Square
A large square set on point inside a square, framed by a wide border with contrasting corner squares; the layout of the classic Amish centre-diamond quilt at block scale.
Economy Block
An upright centre square framed by two rounds of triangles: the first round turns it on point, the second squares it up again, so the three squares nest at alternating angles.
Snail's Trail
A two-colour four-patch at the centre, wrapped in four rounds of ever-larger triangles that alternately set it on point and square it up; each triangle continues the colour of the piece it grows from, so light and dark arms spiral out like a snail shell.
Square in a Square
A square set on point, its corners touching the middle of each side, with four half-square triangles filling the corners.
