This picture shows the reverse side. The top is the reverse side of the traditional mattress stitch (invisible on the "right side"). You can see that it is a thicker seam. The bottom is the reverse side of the seam stitched between the slipped stitches.
If I stitch in the middle of the slipped stitches I can wear Rosetta as a reversible skirt, making the seam visible on both sides. However, after seeing Del's beautiful Dolman Pullover that has the seams on the outside, I'm tempted to do the regular mattress stitch making the seam invisible on the right side, with a bulkier seam on the reverse. What do you think?
