I love this!!! I am much more chaotic. I have many different small bags with varying content. I have a roll-up for crochet with several hooks and many markers, a wool needle and pencils. I also have different small bags with buttons, wool needles, tape measure and again many pencils and markers... (I really have a huge amount of markers, I use them for everything :-D)
When I knit on the go, I often put special packages together with things I think I need... But I seldom have everything with me.
Perhaps I will later make a photo of my crochet roll-up, I am a bit proud of it as it is handmade :-D
