I used the friendship blooms set from Simon Says Stamp for both the images and the sentiment.
I stamped the images with StazOn on Schut hotpressed smooth watercolouring paper 300grams.
I used Distress inks for the watercolouring (mustard seed, carved pumpkin and peeled paint).
The sentiment is heat embossed with white embossing powder on black cardstock I wrapped around the watercolour panel.
The panel it self is raised and attached to the cardbase with foamtape.
