In your experience, what's the most suitable software/app to design a typographic logo?
There's nothing better than pen + paper, kick it old skool!
I always find it difficult to draw my own type, as whenever I try to draw letters I kind of just draw a blank as to what the letter should look like.
Pen & paper, then illustrator.
Pen and Paper, high res photo from iPhone then Affinity Designer. Bish Bash Bosh! Job done!
sketch, sketch, sketch, sketch, sketch then vector.
CorelDraw definitely! You can start from here http://www.coreldraw.com/en/pages/logo-design/ and start learning, it's very helpful! :)
