After working a few more samples this stitch sampler was completed.
In the first row, the top and bottom stitches are worked at different angles. Two looped cretan stitch rows worked together [one over the other] forms the second sample. Two loops are made on the cretan stitches in the third sample. Two buttonhole stitches are made after the loop in the last sample.
I enjoyed working on this stitch sampler. This stitch is very versatile to combine with other stitches. I was not paying attention to the thread colours, they were all polyester threads.
