My stash is too big, so I'm going to reduce it by 123 models in 2023!
Okay, I have to be honest with myself and admit that that's an overly ambitious goal, but it sounds catchy and it captures the spirit of this downsizing effort, so I'm sticking with it.
Here's the thing -- having a large stash (in my experience) presents three very real problems.
First, I'll never build them all. I have 25 to 30 years of good eyesight and hand/eye coordination left to build models, so at my current rate of 5 models per year, that's just 150 models. Even if I double my build rate, that's only 300 models. Suffice to say, I have many more unbuilt models than that, not to mention new kits that we'll see see in the coming years. There's a psychological effect when I realize I can't build everything; it's depressing to look at, for example, that Hasegawa F-111E or the Trumpeter T-64AV and realize I may never build them.
Second, my stash consists of many models that I find less interesting than others, so there's a risk of my wasting time building models that don't bring me joy. This has happened. Time is precious. Shouldn't I focus on the most enticing subjects and dispose of the others?
Finally, I really don't want to leave hundreds of models to my heirs when I go to the Great Hobby Shop in the Sky. I've seen a lot of modelers talk about the disposition of their stashes with, "I'll be dead, so I don't care what happens to my models." That crass attitude ignores the burden that your family or friends will endure to pack, organize, and sell your models.
Just over two months into my downsizing, I can say that selecting models for sale is difficult. Like you, I can point to every model in my stash and tell you how I intend to paint it, the markings I'll use, and the weathering I envision. I bought each model for a reason (at the time), so I'm making tough choices.
Ultimately, I think 60-70 models seems more realistic than 123, but I expect to continue the task through 2024 and beyond. The models that remain on the shelves will be those I'm most passionate about. They are likely to be 1/72 aircraft from the 1960-2000 time period, roughly 25 1/48 modern aircraft from the same period, and 1/35 Soviet, Russian, and Israeli armor. Everything else is a candidate for culling.
I feel good about this. There's very little risk, in fact. As a fellow blogger pointed out a few years ago, if you sell something and then want to build it in the future, odds are you'll be able to buy it again. And, I would add, buying it with a strong, compelling desire to actually build it and not put it back on a shelf.
