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
Work a row of straight stitches of equal length
The 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.
Move 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.
Continue in this manner along the line of foundation stitches. At the end of the line take your thread to the back of your work.
How 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.
