The drawing materials used for the outline are “pencil” and “STAEDTLER pigment liner”. I am not sure if alcohol markers stain or not, because I don't use them very often, but I think the “STAEDTLER pigment liner” I used this time did not stain.😊
With transparent watercolor, coloring time is about 4 hours! With opaque watercolor, it takes more time. If you include the line drawing time, it will take about 7 to 8 hours in total.😊
