Hubby took me around loads of industrial areas to photograph everything and anything, until we were run off one site by a burly security guard, then in the end I settled on items in hubby's workshop ... spanners, vices, lathes etc ... loads to choose from and right on my doorstep too. My chosen shapes were a set of spanners, and its amazing what you can do with them using computer photo software ... I had great fun!
I find the DMC Cross-stitch software (about $20 from Officeworks) is brilliant for charting your designs. I used it for the cross-stitch and assissi patterns, and also for the canvas work. Here are some pics of my samples and the chart created in DMC software for my experimental canvas work
