I had done this stitch sampler as a part of chain stitch varieties earlier in 2012. That sampler is posted here. The method of working this stitch is on SharonB’s blog. First part of the sampler worked this time-
1.The basic stitch is worked in the first row. Two rows of this stitches are worked together in the second sample. One more stitch is added to the basic stitch in the third sample.
2.The first row is laced with six strands of cotton skein. The shell chain stitch is worked alternatively on both sides in the second sample. the stitch is worked in a curve in the third sample.
3. This stitch is worked on bars to get the effect of raised chain stitch in the first row. Instead of working the shell stitches on single chain stitch, they are worked on berry stitch in the second row.in the third row, the shells are worked on linked chain stitch in the third row.
