The Slip Knot quilt block makes for some interesting quilts due to the "optical illusions" it creates when you choose a design.

The quilt layout shown on the left sets blocks and half blocks on point to create a central motif. The additional blank blocks and colourful side setting triangles add an extra splash of colour in this quilt.

Large corner triangles are added to each block shown below in the quilt layout on the right. Careful placement of these colourful triangles creates a "colour blocking" look to the final quilt design.
