my first impulse was drafting w graph paper as mentioned by most here. then the response by quilterpurpledog made me rethink. yes ..i'd go to copy center or a mail box place as they all have nice copiers. i have my oversized patterns done for me at my ace mail center here locally as we don't have copy centers per sé. i am also a fan of difficult set in seams. after you have a copy at the size you want, draw the straight piecing seams as demonstrated by feline fantatics image. but instead of cutting off the offset areas i would do set-in seams for those areas. i love this design & i too think it resembles a frank lloyd wright design, definitely art deco. good luck w your project ..hope you are successfull and please do post a pic when finished!
