Lock and Double Lock Stitch Tutorial

Lock Stitch looks simple but is amazingly versatile. There is also a double version. Both are very quick and easy to stitch, look good in range of threads, will follow a curve or worked row up on row make a wonderful filling stitch.
All that, and (don’t worry I am not going to offer you set of knives) there is the obvious use for borders or as an edging stitch. Also because this is a lacing stitch the lacing thread can be a larger novelty thread which can create some interesting effects.

How to work Lock Stitch

Lock stitch basically consists of a row of vertical straight stitches that are laced.
Use a tapestry needle to avoid splitting the foundation stitches

Lock stitch step 1Work a row of straight stitches of equal length

Lock stitch step 2The lacing is worked from right to left. Bring your thread out on the right side of the first straight stitch.
Pass the thread the needle under the first stitch from the left with the tip pointing right (as illustrated).Pull the needle under the straight stitch.

Lock stitch step 3Move to the next straight stitch and pass the needle under from the left with the tip pointing towards the right. Pull the thread through. This will lace together the first two foundation stitches.Note that you are lacing the stitches and not going through the fabric.

Lock stitch step 4Continue in this manner along the line of foundation stitches. At the end of the line take your thread to the back of your work.

Lock stitch step 5How to work Double lock stitch

Double lock stitch is simply a line of lacing along the bottom of the foundation stitches and then a line along the top.

Double lock worked row upon row creates a very interesting and quick filling stitch.

    The Lock Stitch is one I need to use more; I found it difficult to control the tension.

    I enjoyed using the Lock stitch again and will be using it on my Hussif and an ornament. Seeing the beads on work by others (above) has inspired me to try that too.
    It has been good to be organized at long last and make a folder of stitch examples too.

    I don’t think I ever just this stitch anymore, so thanks for adding it to TAST again.
    Today I shared interlaced up and down buttonhole stitch on my CQ:

    Oooh! I have fun ideas for these. I completed stitch 128 this week. It still needs to be dressed up, but I had fun with this one and plan to play with it more in the future. Thank you!

    I have posted a shot of two TAST stitches on Flickr–interlaced up-and-down buttonhole and double lock stitch with beads. I’ve used them as seam treatments on my latest CQJP block.

      JoWynn I took the liberty of fixing the link to your blog (so if people click your name they can go to your blog) but I am afraid I have lost the web addy for your flickr account you might wnat to add it to a comment so people can visit – sorry to be a bother

  10. Hi Sharon,
    Looking forward to explore this stitch. The details of 128th week interlaced up and down buttonhole stitch explorations are here-
    Thank you,

  11. Like Claire, I find this stitch to be not only visually pleasing, but one that a leftie can easily adapt to stitching, preferably on CQ seam treatments. Thank you,Sharon

  12. Claire Turner says:

    I like this stitch Sharon. It is visually quite pleasing. And I can see potential for a CQ seam treatment, with further lacing between the 2 lines with a novelty thread, and also for added beading. I will try this on one of my blocks. Claire
