Patchwork & Nine-Patch Afghan Patterns (These samples are lapghan size.) Patchwork Squares These five 7” squares can be mixed and matched to create a patchwork afghan. Since the same quick & easy stitch is used for all the squares, the resulting afghan has an overall consistency seldom found in patchwork afghans. These squares are great for exchanges and the size is easily adjusted by changing the number of rows. Floating Squares Use one or any combination of these four 7” squares to create an afghan in which the contrasting squares seem to float on the background. Or combine them with the patchwork squares to make a patchwork afghan. These too make good exchange squares.
