but it seems like one book was out for half square triangle strip blocks too.
just take your square of plain fabric,batting and backing. start sewing strips on only one half of the square through all layers. then flip over and stitch strips on opposite side. that will make the whole block quilted as you go! just can't find the pattern. seems like it was Georgia Bonesteel.
