Here's the updated sketch of the packing list that I posted before my Siem Reap, Cambodia trip. It's just updated with labels.
I had forgotten to include the technical pencil but it turned out that I didn't use that during the trip. There wasn't any time to do any drafting before inking. Most of the sketches that you'll see in the next few days are just drawn with ink straightaway.
My initial plan was to use the Hero pen but the ink flow is just not good enough. I only made one sketch with it and gave up.
I did not use much of the waterbrush. It's difficult to make flat even washes. I use it only when I have no other brushes. Many artists like it for the convenience.
The watercolours are the same palette used during my Spain trip. Daniel Smith watercolours. I'm really starting to like them, a lot. Maybe the fondness actually comes from the fact that it's easier to wet the tube colours as compared to the pan colours. Mine's a 10 colour palette.
One pen that got a lot of use is the Pentel pocket brush pen. It ran out of ink and I used it like a dip brush. Works great. I also found out after the trip that you can actually refill the disposable cartridge with those small Rotring ink bottles with tapered tips. The trick to refilling is not to put the bottle's whole tip in. I guess you can save a few dollars from buying the brush pen refills.
I like to keep it simple and light when it comes to packing drawing tools for overseas trip.
