This sprang pattern is a combination of holes with warp transposition. It gives a 3-dimensional fabric.
The sprang pattern you find in the book “The techniques of sprang” from Peter Collingwood, plate 25.
I have woven through the holes in the sprang fabric with a crocheted cord and have attached real feathers to this cord.
The whole is meant to be a feather for the big bird I want to make for my art project about bullying. So I will have to make lots of them….
