I decided my favourite colour this month is blue, and used the fabulous Floral Watering Can from this month's sponsor Delicious Doodles for my base image. I recently fell in love with Letraset AquaMarkers, bought the entire set, and played with them some more for this card.
I started by printing two copies of the image onto 90gsm watercolour paper using my laser B&W printer. I added AquaMarkers to the crosshatched areas of the design (as these will be the darkest) and dragged the colour across the rest of the space with a waterbrush pen. I added extra layers of colour where needed by allowing the first layers to dry before painting on colour picked up from a palette (draw on a plastic sheet with the AquaMarker). That's how I built up the mottled watercolour effect on the can and the shadow.
For added depth (not easily seen on the pic) I coloured in the second copy and cut out selected items, edged them in black and layered them decoupage stye onto the flowers. Try to choose things that aren't overlapped by anything else and you'll get the foreground elements perfectly.
Can - Pebble Grey

Let me know if you'd like a more in-depth/video tutorial on using AquaMarkers. I think they're fab!
