Back to alcoholbased Markers

It is not that I don't like painting with Gouache anymore. From time to time I have to switch to another medium, sometimes because I watched an inspiring video dealing with that medium, sometimes because I am looking at the shelf in my studio noticing the number of markers I've got. 

I love to do abstract pieces with my markers. I notice, however, that it takes me much longer to finish a piece. I often look at the work in progress when I am sitting at my breakfast table, thinking about which colors to use next.
