The fabric is actually a very lovely lined, cotton skirt (from Per Una if you care) with a fabulously zingy print in coral pink through to red and brown for definition. I simply single crocheted a chain long enough when measured around her neckline and off I went. The beads were actually removed from the waistline of the skirt so nothing was wasted :-)
Not my usual thing but it kept my hooks busy, I upcycled and now my daughter has a beautiful one off frock. All happy!
