Tessellations 6: Quadrilaterals---Oddrilaterals

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

Carol Gilham Jones, Ginko Leaf
Pieced and Appliqued

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.
