My latest design uses a couple of musical notes. This would make a great gift for someone who loves their music, or is maybe a singer in their local choir. Why not use a book with a musical theme, such as a biography of a famous composer.
The pattern only uses 224 folds (448 pages) so can be completed in 2-3 hours.
The pattern for this "Musical Notes" book folding design is available to download from Etsy.
