I've not taken part in the butterfly challenge recently (sorry) but as this is the last one of the year I've decided to play along. The letter is 'W' and the card style is 'Windmill', see details below
I've used the windmill idea along with colours of wheat, and wine as well as words (text papers) and of course there have to be some butterflies. Couldn't manage the wisteria colour. There are prizes to be won so worth popping along to see the inspiration from Mrs A and maybe have a go yourself. See full details HERE.
