Free Pattern – Streak of Lightening Quilt Block

The Streak of Lightening quilt block is a great block for using up those skinnier strips you’ve been saving and finishes at 10″ square! It is similar to a Log Cabin block (you can find my tutorial for a Log Cabin block at

Let’s do this!

Sewing Directions:

Four Patch Unit:

First off, using the 2 Light/White 1.5″ squares and 2 of the Dark/Black 1.5″ squares, make a simple Four Patch unit as shown in the picture below. You can find the tutorial on making Four Patch units at

Strips Sets:

With the remaining 8 Dark/Black 1.5″ squares and the 3.5″, 5.5″, 7.5″, and 9.5″ rectangles, sew strip sets as shown below. Press the seam allowances away from the Dark/Black square. I started out pressing toward the black square, but in the end it was better to press away from the black square – so I won’t be showing pictures of the back of the block until later on – Lol!

Block Construction:

Sew a 1.5″ x 2.5″ rectangle to opposite sides of the Four Patch unit. Press seam allowances toward the rectangles.

Using the two 4.5″ strip sets you made above, sew them to the sides of the unit you just made. The seams should nest nicely and you can press the seam allowances toward the outside of the unit.

Now sew the two 4.5″ x 1.5″ rectangles to the top and bottom of the unit and press the seam allowances toward the outside of the unit.

I got so immersed in sewing I forgot to take a picture! The missing picture would have shown the two 6.5″ strip sets being added to the unit. Again, press the seam allowances toward the outside.

Next, sew the two 6.5″ x 1.5″ rectangles to the top and bottom, pressing the seam allowances to the outside of the unit. You will continue in this fashion until you’ve sewn all the rectangles and strip sets.

Here’s where I started pressing the seam allowances correctly.

All done except for the pressing!

In Conclusion:

I think this is a great block to use up skinny scraps and not have to worry too much about color placement. However, when I do this block again, I probably won’t use black prints in the rectangles – not enough contrast between them and the black squares. 

I hope you have enjoyed this Streak of Lightening block. If you give it a go, feel free to comment about it.

Happy Quilting!

      Hi Cathy,
      When I do another quilt layout post, I’ll use this block and show different ways it can be put together. Elaine
