Don't sell your Modeling Stuff, just put it away so that you will have it to come back to. I can't build anything right now and it is driving me nuts!
I have always built plastic models, mostly Model Cars, and Military Models, but I also enjoy building Military Aircraft. I keep from burning out by changing between them occasionally.
Even while I was Racing Grp 7 Slot Cars as a Pro in the seventies I built plastic. I still buid and race Slot Cars, and I have a fully detailed 1/32 Track Layout, photo of my Track are posted in the Model Racing Section of this Forum.
I have never sold my Models, or tools, but I have had them destroyed twice, due to home fire and a storm, and I had a very hard time replacing them.
