Seven-patch quilt blocks

A seven-patch block is drafted on a 7 × 7 grid. Bear’s Paw is the best known: four paws of half-square triangle claws round a cross of narrow strips.

Seven doesn’t divide 6″, 9″ or 12″, so at those sizes the pieces fall between the lines on the ruler. Make a seven-patch block 7″ or 14″ (or 10½″) and every piece measures cleanly; each page below names the sizes.
