This is a picture of margaritas, this Riolis kit (Russian) brings great appearance with only 11 colors and no backstitch at all.

Here is its back which I tried to make as neat as possible (actually it looks like ||| when zoomed in):

And this is a different type of work, double-sided bookmark with stitches as an x in both sides (my initials btw):
Side 1/side A (front side as in chart)

Side 2/side B (back side as reverse of chart)

Just for you to compare:

A close-up view for you to see that in the back they are not ||| but real x stitches

Actually the very 1st time when I attempted to do something like this, I thought that it would be much more difficult than it turned out to be. I really want cross-stitching lovers to enjoy doing this. It would be somewhat complicated and time-consuming, however it is not very floss-consuming and definitely easier than having perfect/super neat backs. Also, the works are marvellous.
