This is a modified Kansas Dugout block where the intersection of the strip and the triangles does not meet at the center of a side of the block. It is about a 3:1 ratio or a 4" finished block with a 3" finished triangle at the corners. I used the signature die on my Studio die cutter but you can get this by using a 4.5" square with 3.5" squares as the connector corners. The photo shows 4 Kansas Dugout blocks. Now one unit of the block is commonly called Kansas Dugout.
I had a lot of people ask about this photo I posted yesterday. It is the same block that is in the corners on my X and + quilt, in fact these are leftover pieces. They are 4" finished squares with 2" finished triangles or a 2:1 ratio. This means you would cut 4.5" squares and 2.5" squares to do connector corners.
When I was showing the construction on the X and + quilt I showed that I used triangles instead of squares to create the connector corners. I used the ruler to be sure I had it square on the corner before sewing. I hope this answers all of the questions that were asked. Some were no reply commenters so I couldn't reply to them directly.
