This image shows a series of sketches in pencil (5 minutes each) in which the main focus is studying two different textures - glass and corduroy.
The glass vase has many highlights, and is also a reflective surface. Probably the best way to create the impression of shine is to use straight parallel lines while applying shadows to the drawing.
As any fabric, corduroy is a very detailed matte texture, and therefore it should be tackled in an impressionistic way, by just hinting the parallel fibers.
This still life drawing is a study of the two textures put together in a scene. It was done in pencil and took 30 minutes to complete.
The fabric isn't fully drawn, containing many empty areas, but the drawing still manages to give the idea of vases placed on a striped material. The scene needs more details and shadows though, because the glass doesn't seem as shiny as the real thing, and the cloth in this drawing seems really light, while corduroy is a thick material.
Composition wise, the scene seems balanced and the objects interact in a visually pleasing way. Planning was done with the help of construction lines which are still visible on the paper. This also helped with getting the proportions right.
