First I found a school textbook for needlework, published 1963, that took me down Nostalgia Lane. Although very thin, it is full of information ranging from subjects such as different kinds of fibres, the washing and care of clothes, the colour wheel, wardrobe planning as well as embroidery stitch instructions and clear illustrations for how to mitre a corner. What a book from the early 60s lacks, is inspiration. Skill and knowledge were more important than creativity. These days the focus is likely to be on encouraging free form, and clear how-to instructions are seen as unimportant. What we actually need is the combination of both.
My next find was this lovely braid/ribbon that I picked up in a charity shop:
I hope you will see it on my WIP sooner or later.
