In addition to being used for inserting lace or joining lengths of linen, the Plaited Insertion stitch can also be used as a decorative surface stitch. Out of curiosity I wanted to know how a corner might be turned when using this stitch.
I used a small mirror to create a right angle at different places. The above corner looks beautiful, but I cannot figure out a way to embroider it. Whereas I was able to embroider the corner below.
I stretched a piece of linen with 13.5 threads per cm in a hoop and withdrew two fabric threads eight threads apart for better orientation. Using coton à broder No. 16, I started to work some three-group stitches. I decided to not make stitch placement marks, choosing to place the stiches one fabric thread apart instead.
I am not 100 percent satisfied with the result – the guide lines are a little bit distracting and the distances between the groupings are not quite even – but as a practice piece it is good enough to see that working a corner using the Plaited insertion stitch is possible.
