Beth continues her great work in re-creating ancient drapes:

"The aim of this drape is to recreate a picture I'd seen from the Lepakshi temple in Andhra Pradesh, painted during the Vijayanagar Era (1346-1565). I've found very few pictures of this era, and I've only seen this sari on women. I took a 9-yard sari, and my experience draping fishtail saris to attempt this look. After quite a number of faulty test-runs I came up with this process, which has worked for a reasonably active day."
