I back stitch a lot, anything that is going to be handled......because they always seems to start to unravel as soon as I touch them. I especially do the seams in my borders, sashing and bindings, yes I know they will be intersected by other stitching.....but I am so old school....and would rather be safe than sorry....and with todays machines it only takes a second to push the button and go back a couple stitches...
