Putting pieces of fabric together to create a larger fabric. That seems to have been more rule then exception during the Middle Ages.
Matching a pattern in the fabric was possible a luxury not even the highest nobility and the church could afford.
Here is a Danish chasuble from 1470-80 with some piecing that gives us a bit of a headache but also a smile of relief. If they weren’t perfect then, we reenactors can take a deep breath and let go of our modern eye too. The chasuble is made in silk velvet.
It can be found in the collections of the National museum, Copenhagen, Denmark
