No drawings but sketching more!

I have been focusing on my knitting projects lately, like I write before that is something I can carry with me everywhere.
A sketch book is the same. Well the idea of a sketch book is possible something you carry with you and any time a idea come to you, you put it down in there.
I have been using it while on platform, hidden in my uniform jacket, when I worked at Cannon Street station, but at London bridge station where I am now, it is not a second left over for me to write down my ideas. I get them, but have to save them inside my head until break time or home time.
So this is the kind of drawings I do at the moment!
