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.
