1. Do you think that being a railway enthusiast is a good hobby?
Yes
2. Do you find it easy to make models?
This isn't that easy. It depends on what you are making and the effect you're trying to achieve. Sometimes is takes several attempts of trial and error to get it right.
3. Do you like making models on an everyday basis?
If only I could! Sadly, I might get a couple of hours a week if I'm lucky.
4. Have you ever made a model before?
Many when I was younger and had less in the way of commitments. My current project is still ongoing after six weeks with little input. It gets that way sometimes. Work has to come first.
5. Would you like to own a railway model?
Yes if I could afford the space needed.
6. Would you take making models as a career?
Probably not. There's not that much call for it as a career I don't think - certainly not in the kind of way as to make a living at it. Buying and selling perhaps, but not making.
Hope this helps and good luck in your project. Feel free to PM me if you need anything further.
