The green marks above were made with a rolling stamp [no 83], which I then outlined in pen and colured the rest of the page with brush pens.
I've posted a couple of pages from book 15 but this is the first page.
Rolling stamps 72 to 75
The first two are from different parts of the same wallpaper
The bottom two are parts of the same wallpaper too, but the top roller is made from two torn areas of wallpaper.
