Some people work directly into a sketch book but I can't draw and my writing is illegible - so I have developed the habit of making my own books to put everything in.
This is the book for the Kandinsky wall hanging. The cover is yet another left-over [I dyed a lot more fabric and thread than I needed]. I spray mounted it to pelmet Vilene and then machine embroidered and lined it. I have used card in the past but you can't sew into it, so you have to lace the fabric over the covers which is lumpier and more work.
I inserted the pages and bound them all together with a sort of Japanese stab stitch in embroidery thread [more left overs].This is a page from the book, showing some of my design ideas for the different pieces of the wall hanging and a section from the diary.
