To make a Log Cabin Variation of the Wonky Star Block
2.5 inch square for the center of the Log Cabin block
6-8 strings (strips 3/4 inch to 1.5 inches wide) They can be symmetric widths or asymmetric. It's a modern block so it's up to you!
The center block for the Wonky Star needs to measure 5 inches (finishes at 4.5 inches)
Cut the first 2 strings 2.5 inches and sew to the right and left sides of the center square
Measure the width of the block you have just sewn
Cut 2 more strips to and sew to the top and bottom of the block.
Continue to build this block until you have a block at least 5 inches square. If your block is larger than that, trim it to 5" square. This block ended up asymmetric when it measured 5 inches. That's fine.
Now you are ready to make your Wonky Star. I recommend that Victoria Gertenbach's excellent Wonky Star Tutorial to make the Wonky Star block.
