|Nine Patch||Uneven Nine Patch|
Free Quilt Block Pattern
The Twisted Ribbon quilt block is a seven patch design, (because it is drawn on a 7 x 7 grid), but is constructed as an uneven nine patch simply for the ease in the sewing.
This lovely block gives the illusion of its name -- a ribbon that is twisted and thereby showing the "underside" of itself.
