I'm posting pattern instructions here for this block that I don't have a name for.
I call it "loglike", because you can arrange them the same way as with log cabins.
For more variety, you can can arrange each sub-block individually rather than my full version here, but I've written down this pattern for the Quilt Block Swap 5
, which aims for 12.5'' blocks
So, let's begin!
For each block, you'll be making four of these.
OF EACH fabric, per sub-block, cut:
3 pcs 2,5'' square
1 pc 2,5'' x 6.5''
Take one of each color square and sew diagonally across. This makes the center bit. Cut off excess fabric and press.
Sew one square of "opposing" color to two sides of this piece, according to the picture, and press. That makes the middle strip.
For the left and right strips: Take one rectangle and one square of opposing color, and match up along the edge. Sew diagonally according to the picture, cut off excess fabric, and press. Repeat for the other rectangle.
Put together according to the picture of the sub-block.
Make four sub-blocks, and put together according to the larger picture.
