Not exactly a new hobby but I got back into drawing, something that I had not done since 2018, if that counts. Is Gunpla related to gundam plastic models? sounds like fun
Guitar. Found one for pretty inexpensive and just put in the time and practice. It's really difficult to learn but so rewarding once you start to really get it.
I wanted to get into wood work, like carving and stuff, but the first time I tried, I didn't have the right tools and it was a mess. I was a little disappointed in myself and gave up. I want to give it another shot, but I've been so busy lately that I don't have time. A woodworking lathe would be awesome though
