Irish Chain Quilt Block
Also known as Single Irish Chain.

Irish Chain is a traditional two-colour block whose squares form a clear diagonal chain across the design. This 12-inch version uses only squares and rectangles, making it straightforward to cut and piece.

Notes
Assemble the squares and rectangles into rows or sections, then join these while matching the seam intersections. Accurate cutting and a consistent seam allowance matter, as misaligned squares interrupt the diagonal chain; pressing adjoining seams in opposite directions can make the joins easier to match.
