How long do you need for a picture ? Such as for Spider Gewn Sketch
Thank you so much!
For a sketch it takes something as 6 hours (a little more because oil painting need to dry; with the drying time it takes 3 or 4 days for the sketch to be completed).
For an oil painting on canvas, it takes something as 10/15 days.
