Those who draw outside know the importance of the weight of the material when going out to sketch.
Often the stools found on the market are comfortable but are quite heavy.
And then to the weight of the stool, you have to add that of the drawing materials, paint, pens, notebooks, a small container for water, and it is practically impossible to go out with just one pen and a notebook.
We feel like taking it all with us.
The other day, while wandering in Barcelona looking for a subject to draw, I found this mini portable folding stool, in a fishing store, in the Born district. Unfortunately this shop has closed. A mini folding stool, portable and light!
It can be found on the Internet, this stool is from the Robens brand. Lightweight and resistant it would support up to 130kg according to the manufacturer.
And also antoher brand, on Amazon.
