This is the Grandluxe Etcetra Sketchbook. It's a hardcover with 80 pages of 180gsm watercolour paper. The cover is clothbound and comes in various colours: blue, green, black, pink. It also comes with an elastic band closure.
It has only landscape orientation and comes in sizes 5.8 x 8.3 inches (about A5), and a smaller size of 4.1 by 5.8 inches.
This was the sketchbook I brought to Cambodia for an intensive sketching trip.
The thing about clothbound sketchbooks is they can get dirty easily. Mine's already quite dirty because I had to put it on the ground sometimes. The clothbound does feel nice to the touch though. But I would prefer non-clothbound sketchbooks in the future.
The actual binding of the sketchbook actually does not attach to the hardcover spine.
This sketchbook uses the glue-type binding. The pages are meant to be torn off. As such, it should not be used as an archival sketchbook.
I had mistook this for a durable sketchbook and brought it on the trip. Bad mistake. So now for me, the inner cover actually came off from the glued spine. That's exactly what happened to mine, so I guess I'll have to glue it back again.
The pages can open flat and that's great if you like drawing across the gutter for a double page spread.
The paper is 180GSM so it's good enough for watercolour. It absorbs water well and the watercolours looks good.
There's some wrapping when too much water is applied but it's not a big issue. I would not have too many glazes because of the thickness of the paper.
Ink on paper might feather depending on the usage. If you leave your pen tip on the surface for too long, the paper will absorb the ink and feather. If you use brush pen for inking, or apply a larger amount of ink other than drawing lines, then it's going to feather also. So the techniques to prevent feathering with this sketchbook is to always keep your pen moving, and not to use pens that deposit a lot ink — fountains pens are fine but not those that have bigger tips.
This sketchbook is good for casual or watercolour practice. If you need the sketchbook to be archival, you need the pages to be stitch bind.
