I have been having trouble uploading my photos and so I am sorry it has taken me so long to get back to my paper block. As you can see I have stamped a small image in each of my inks from Simon Says Stamp on this block and although it's not clear I have also written the name of each colour. It is just a simple and small way of carrying my colours with me.
If you haven't been in a Muji store yet, it is really worth the visit. They have a little bit of everything but there stationary and organization products are really cool (and functional). If you are in the Toronto area, there is one at the Atrium on Bay just across the street from the Eaton Centre and one in Square one.
