I've been interested in upholstery especially with repurposing furniture with wacky fabrics.
how is it going. What does it take to do that
Well you need coil springs, it's done by hand and it can be stapled in to existing furniture. It takes practice.
Okay. How long have you been doing this. Can you learn it on your own?
I haven't, but you can! You need synthetic material depending on what you like, it is up to you!
That is cool to know. Maybe  i can try to learn it myself. Can you study chair making in the university? 
I guess you could since it is under interior design, that way you can learn the basics!
