 Nine Patch | Uneven Nine Patch |
The Uneven Nine Patch style of quilt block is so named because not all of the nine individual patches are the same size as is the case in a regular nine patch quilt block. This style of quilt block is often used in 10" quilt block to make the math easier, but you will find this construction method in many other quilt blocks as well.
Proof Positive
Free Quilt Block Pattern
The Proof Positive quilt block features a patch that is not used frequently, but is a step up in difficulty from the half square triangle unit. It is often called a three quarter square triangle patch, as it is comprised of three triangles to make the square.
Half square triangle pieces are used as well as quarter square triangles to make the four patches (the three quarter square triangle units) required for the centre of the quilt block. The completed block is constructed as an uneven nine patch.
