The scales are kind of curved Muria's ideas good so you would just have to sew the strips rather than each individual scale . i think you would start at the bottom and work your way up so you cover the strips as you go.
This pic was from ebay its a LIP SERVICE item. My sister found it i really liked it and thought that someone might be able to tell me how to make it. there are front shots but there black on black so there kind of hard to make out.
