Recently I found a MOC made by Headzsets from Instagram, in particular this interesting structure from his EVA work. Here is a picture of his structure:

How does he have two 1 x 1 x 2/3 slopes like this? Are there any sets with this kind of structure that I can buy on the market so I can learn this building technique?
Just to add a little to the answer by TheBrickBlogger, the blue piece holding the purple 1x1 slope is likely this one:
Here is a really simple example of one of the many ways this can be accomplished:
The hollow stud allows positioning to be "jumped". Hope this is helpful :)
The black cheese-slope is attached to the stud below, and the purple cheese-slope is attached to the upside-down stud above it. The two cheese slopes are not attached to each other, but are held in place by the studs and the other pieces around them.
Cheese-slope techniques have been extensively researched by LEGO fan Katie Walker, who is well known for her cheese-slope mosaics. Her research into the techniques has been used by many other LEGO fans and also published in books.
If you would like to understand the techniques better, I highly recommend the following article by Katie: Cheese-Slope Mosaics: A Tutorial It includes extensive explanation of the techniques as well as pictures with demonstrations.
