I love watercolour with emboss resist. I love a rainbow. And I love my Zigs. This card, therefore, is a triple threat.
I used the Highline Ironwork Background stamp from Hero Arts (white embossed onto Canson Montval watercolour paper), along with the Thanks Stamp & Cut set, also from Hero Arts. I chose some vibrant colours from my Zig Clean Color Real Brush markers and added heaps of water, using a paintbrush to fade the colour out towards the bottom of the card.
