This week’s SBQ is:
Yes. It's probably one of the reasons I am so slow. I don't use a laying tool, at least on cross stitch, though I do on needlepoint. I don't always railroad the bottom cross either, but I always railroad the top stitch by bringing the needle down through the middle of the two threads. About 95% of the time that is enough to have the top two threads lie parallel. A small percentage of the time they still twist and I might let it go or I might use my needle as a laying tool. What I will do is "fluff up" the stitches if I find that some of the stitches are not covering the fabric adequately. After much of the stitching is done in a section I will look back at it and see if there are any stitches that are really twisted enough to not properly cover. I will work my needle around them to see if I can make them lie flatter or cross differently to cover more. But railroading while top stitching is usually enough to make the thread cover.
Do you railroad?
