Nice have an entire Sakura Section.
I received a Pocket Box at the Del Mar Fair, 18 color as a Donated Award. This is a really good design and the "student grade" paints it came with were fun to work with. Not exactly sure what pigment codes are involved so I just used them for practicing and removed the plastic insert which holds them.
The box is actually a wonderful design, with the choice of where to put the mixing tray. The bottom portion isn't flat, but has ridges in it, so I cut out a piece of sheet metal to exactly fit it. I then used magnetic tape which I affixed to all my half and full pans, then arranged whatever colors I need into the box. The magnetic tape sticks the pans to the field box wherever I place them. The depth of the box is such that the mixing tray actually snugly covers the pans when it's in place which should prevent some pigment migration.
Right now this is some cotman on the left ( they include pigment codes ), and my winsor newton artist grade staining colors on the right. Also have some QoR Titanium White and Transparent Yellow Oxide. I have some Altoids Tins which can hold any other colors I want to use. I basically can quickly swap out colors on a whim. I also put magnetic tape on the sponge so it stays in place.
I got a book light from the dollar store, and cut off the clip that came with it. The flexible neck fits right into the holes the mixing tray fits into, and now it fits into the front section of the field box. I also keep my waterbrush, a short supracolor pencil.
The water brush is very nice, probably worth more than the entire set. I'd still like to be able to use regular brushes since scrubbing does not seem like it agrees with this brush, and figure out a very short water container that fits into this box. Already having a lot of other artists asking me about the brush and saying they are going to get one.
I also went and put velcro on the bottom of the box. This acts to protect tables from being scratched I rest the box on, but also lets me use it with my book mark insert
for my sketch book.
All in all a very nice set, really glad I didn't do as well in that art competition, by not even getting 3rd place I managed to get a really nice tool for making art that I will have for the rest of my life. Hopefully now that I have this nice field box I'll get more practice in and end up doing much better next competition.
