Sixty Degrees of Tessellation IV
by Carol Gilham Jones
Carol's been exploring tessellated shapes and color.
The shape has 4 sides---it will tessellate or tile.
A different angle
but one piece covers the surface

It's roughly the same shape as this:
A square divided equally with a line.
The new shape has four sides: Right angle in two corners.
A vintage quilt from about 1950? with a different take on the shape.
It's half a rectangle.
And half are flipped over.
Two make a tumbler, so a tumbler might be an easier shape to work with.
And like a tumbler it can be any proportion
as long it has four sides.
But if you had a good sense of direction and were working on a design wall you could do many things....
Most of which would involve a lot of thinking.
With 4-way mirror-image rotation it's a quilt block.
But it doesn't have a BlockBase file under four-patches where it belongs.
Here's an odd-shaped quadrilateral that was actually published.

Rotation in the block. Rotation in the repeat.
