I've been trying to get some DIY jobs done in the house, but I wouldn't call that a hobby. I have also been spending a lot of time gardening (also work, but also very relaxing). That, and trying out many new recipes.
This is going to sound plain weird to a lot of folk but, years ago, a photographer I worked with gave me a large dolls house. It had some random bits of furniture in it but, (like my full sized house when I bought it) needed a full renovation. It had clearly been well used over the years. In my formerly super hectic life, this renovation was not a priority, so I set the dolls house down in a suitable spot and did nothing with it. Many guests admired it but I hope not too many of them looked inside because it's a mess.
Anyway, during lockdown, I decided to start on this long-overdue project and got quite into it. This is a hobby that I know most people find highly suspect but, if you are into history, architecture, costume history, interiors, upcycling and learning new crafts, like I am, it's an excellent way to combine all of these. It's also a way to experiment with interiors ideas without having to commit to them on a large scalse. I can't tell you how strong the urge is to redecorate rooms in my house because of my love for interior design, but it's kind of stupid to spend time and money redecorating rooms that don't need it!
