Offset Log Cabin Quilt Block Tutorial

red and white offset log cabin block with title.

The Offset Log Cabin block is kind of fun.  It is almost the same as the regular log cabin block, but the light and dark bars are different widths.  This results in a curved look, more or less depending on how much the difference is.

For the Log Cabin Sampler quilt, you need seven of these blocks.  For the mini sampler, you only need three.  This block uses 2-1/2″ wide pieces, which is different from the other blocks.


Dark fabric:

  • seven [three] 3-1/1″ squares
  • seven [three] 2-1/2″ x 4-1/2″
  • seven [three] 2-1/2″ x 6-1/2″
  • seven [three] 2-1/2″ x 7-1/2″
  • seven [three] 2-1/2″ x 9-1/2″

Light fabric:

  • seven [three] 1-1/2″ x 3-1/2″
  • seven [three] 1-1/2″ x 4-1/2″
  • seven [three] 1-1/2″ x 6-1/2″
  • seven [three] 1-1/2″ x 7-1/2″


If you’ve done a traditional log cabin block, this layout should look pretty familiar.  The 3-1/2″ square is in the centre, and the bars rotate around with light on one corner and dark on the other.
