Jetnica -- your extra block is awaiting completion of an upgrade in the software of my sewing machine, so please be patient with me. Remember the old days when sewing machines only had foot pedals -- now they have computers that beep, bing, and flashes me angry faces when I make a mistake. If I still don't do it right it shows me a video. Nice to know that I'm being put down by a machine -- at least I still control the on switch.
