Here's a comparison of 2 different colorways for this same Quilt Block.  I saw it on a YouTube tutorial by Jenny Doan of MSQ.  She called it "Two Step". It's a quick & easy block to make.

Here are each of them, the 2nd one first.

The first of these I made.

 

The Sonja’s Window quilt design (originally from 3 Dudes Quilting)

10/24/24

The First is the original I made:  Blues for 3 Dudes Quilting (sashed and bordered);

The Second, the top I had finished in Apple Green / Maroon Batik (from Janice). (Has slimmish borders but no sashing); and

The Third, the recently completed Cranberry, Aqua & Green (also sashed, and bordered with corner blocks).

All based on premise of 2 squares, 4 jelly roll strips sewn together side by side. Put them right sides together, but w/ the strips of one block perpendicular to those of the other, then sew a ¼ inch seam all around the outer perimeter.  Then cut them diagonally corner to corner (NE to SW, NW to SE) & open to reveal 4 different blocks which can be assembled into several different layouts.

The top above has been long-armed by a Friend and awaits binding, since my Sewing Machine is down.

And the 3rd one, is done, below. 

Potato Chip Block

So named because one finds you can't make just one. The individual pieces (called bricks or chips) measure 2.5 x 4.5 inches. 

I made a couple of blocks & a couple more blocks & pretty soon I had a beautiful collection of blue & white blocks.

 

Though I admit to being partial to blue, I love how this Quilt came out. And I really did find making these blocks rather addictive.
