Is it possible to make a "cute" set look elegant?

[willwork4stamps]

I'm making thank you cards for my son's teachers as end-of-the-year gifts. One of those teachers is his music teacher. The only "music" set I have is Jazzed Up and the matching wheel, Jazz. This set is cute, not elegant. Any suggestions on how to make it look "more grown up"? In the other sets of cards I've made I've used Petal Prints and RIW. TIA!

I would just suggest using darker colors...I think that would help it look more elegant...HTH! Happy Stamping!

I think there are many teachers that would be more than happy to get a cute thank you card. Just the fact that you took the time to make the card will be appreciated by all.:-D

Maybe embossing powder? Black or gold embossing always looks elegant to me.
