I understand the dust. Something I use is metal files. I stroke them until they load up then wipe the "dust" out on a towel that is on the seat of my chair. Something else to do is fit the parts carefully and do a fair amount of test fitting. On some kits I remove the alignment pins to get a better alignment, Once done you could take a sharp scraping blade and shave the seam down. You can also fill the seam with CA and add accelerant to it, Keeping the fine dust in the air down is of the most importance to you I am sure. I do a lot of scraping and carving which makes shavings but not necessarily dust. Something to ponder.
As to the pattern, it is really up to you and what you really want to attempt. They all look interesting. The squiggle one would be one heck of a challenge on a 1/32 scale plane. On 1/72 it would be insane.
Hey Eric! We need a video demonstrating wet sanding. Yeah it can make mud, but the point is to keep adding water and rinsing and wiping away the "mud". If it is so thick that that it is like a paste you need to dip the paper in the water bowl and rinse it out. Also it is ok to take a paper towel or other item to wipe off the "mud" as it gets thick.
The trick is to use a fair amount of water. The water carries away the "dust" rather than blowing it into the air. Hold the model so the extra water with mud in it drips into the bowl of water and keep dipping the sandpaper into the water to keep the area VERY wet.
Also a couple of drops of dish soap in the water will help.
