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.

Twisted Ribbon

Sample Quilt Layouts

The two sample quilt layouts featured below using the Twisted Ribbon quilt block present very different results.

The quilt layout shown on the left used an on point setting of the blocks with lots of extra sparks of colour in the form of the large corner triangles attached to each block. The careful placement of those colours add additional interest to the quilt design.

The quilt layout illustrated on the right uses a standard side by side block setting to produce the illusion of a meandering "ribbon" across the whole quilt.
