. . . may be making at the next meeting:
First 2 pics, a warm-up exercise and a chance to try out the basic things done when making a book. Easy sizes clockwise from top left : A4 card - half A4 card - one quarter A4 (postcard here) and one third A4, and up to, say, 12 folded pieces of paper.
Moving on, using the basic technique, books with more than one 'signature' (folded bunches of pp.), - Another possibility: use an old journal quilt (or other fabric piece) for the cover.
Basic cover - A4 card, (here printed on)
or measured and cut out of a side of a cereal box, cut to size and covered with painted paper.
4 - 5 signatures
each of which gets stitched in one at a time, and various straightforward patterns are possible.
Some others are quite complicated and involve having more than one signature being stitched in at the same time.
If the book is to be fitted into a removeable fabric book cover, then the cereal packet doesn't need any paper or paint, and the stitching can be simple as it is invisible inside the cover.
So, hopefully this will help a bit in deciding whether to try making a book, and what sort of book to go for.
