Grids = patches

Quilters think of a grid less as a group of lines than as a group of squares — that is, patches of fabric — so we almost always describe quilt blocks by layout, not by the grid size.

Large center squares are typically based on a 4x4 grid with 16 squares. A block based on a 2x2 grid, with 4 squares, is usually called a 4-patch too — sometimes a "double 4-patch."

9-patch. Medium center squares are usually based on a 3x3 grid with 9 squares.

5-patch. Small center squares are often in blocks based on a 5x5 grid.

1-patch. If all the patches are the same shape and size, the block is called a 1-patch.
