For this training I chose to work on a planning interface.
Due to not having all the information yet, I 'quit' at medium-fidelity wireframes and have not gone up to high-fidelity wireframes (I might add them later). If I would do hi-fi I would probably use Balsamiq.
The training was very interesting for me because I want to start with drawing wireframes faster and more often instead of immediately using a tool such as Balsamiq.
Ps: I should try to improve my drawing an writing skills so that they do not look like the work of a four-year old.
