Cotton Gold has multi-colored sequins in it (not sure it has cotton though) and will make a stunning wrap. Sequined yarn has come down in price considerably over the last several years and it is quite reasonable to make a lovely lacey wrap with one of these yarns.
We also have Event, which is softer in tone and touch – seems a bit of mohair is in the mix. And in case you are wondering, knitting with these yarns is no different than any others – the sequins really don't make it difficult at all.
Everyone needs some glamour once in a while – so try one of these out and be prepared!
