This is a card that I put together recently as a sympathy card (I stamped a 'thinking of you' sentiment inside) for a friend who had lost a relative very special to her. I had coloured & assembled the image panel a while ago so am a bit sketchy on the colours I used so I'll go with 'pink & green'. The blossoms are from a retired set called 'Indescribable Gift', the darker section of flowers is stamped on vellum and coloured with markers on the underside, then cut out and adhered to the larger image. The image is stamped on a newsprint DSP and slightly coloured using chalks (retired - you could use pastels or colour lightly with pencils for the same effect) and then outlined with a chalk marker (also retired but a white pencil could give a similar effect, maybe even your dressmaking chalk pencil if they still make those???). The DSP is layered onto a piece of Basic Black cardstock and the card base is Very Vanilla.
I also made a square envelope using the envelope punch board to fit the card.
