Tessellations 2: Four-Sided Shapes

BlockBase #131a
Hit and Miss
I've been sorting my single-shape pictures, using BlockBase numbers.

They tell me any quadrilateral will tessellate or tile, meaning you need only one pattern shape to cover the surface.

The basic quadrilateral is a square--- So basic I forgot
to give it a BlockBase number under one-patch quilts.

BlockBase #2286b
Postage Stamp or Trip Around the World
But I did give them a separate section with pattern classified by
shading rather than shapes.
BlockBase #2276-2299

BlockBase #2286c

There are many ways to shade a quilt of squares.

Not in BlockBase

The trouble with indexing quilts of just squares---
when do they become a regular old block pattern---a four patch or a nine patch like the one above?

Moving on......

I started the four-sided category with rectangles and focused mostly on shading and placement.

The common early-20th-century throw of wool tailor's samples.
This is often called Stacked Bricks today.

Any rectangle, whatever the proportions, will tessellate.

Early-20th-century Hit and Miss

Late-19th-century charm quilt.
No two pieces alike?

1 piece; 2 fabrics

Names for #132b I found in print when I wrote the original Encyclopedia of Pieced Quilt Patterns about 1980:
  • Old Garden Wall
  • Streak O'Lightning
  • Zig Zag
  • General Sherman's Quilt (?!)
  • Depression Quilt

I suppose a Depression Quilt meant a functional,
tied throw made of old clothes.....

Pattern on the diagonal from about 1900. 
I didn't give it a BlockBase number
