Interesting...just yesterday, I was attempting to wireframe an idea I had and found myself hopelessly lost (I'm not a designer). While in the past I generally used quick sketches, it looks like you advocate a more detailed approach to wireframes, where they almost look like the finished product on paper. How do you trade that off with rapid iterations and the time needed for re-drawing detailed drawings?
I DO NOT recommend that. I recommend quick sketches until an idea is clear. That's why I go pencil -> thin pen -> thick pen. I only move from pencil to thin pen when an idea is clear, and thin pen to thick pen when the actual visual is clear.
Aah I see, your screenshots already looked quite detailed to me. I guess what I've been doing is more like scribbling rather than wireframing.
:) try drawing frames. That's what I use the business card for. It definitely helps to organize thoughts a bit.
