Garden Shed Easy Watercolouring. As soon as I saw the Garden Shed Stamp Set in the new Annual Catalogue I knew I had to buy it. I have been trying to get my head around exactly how I wanted to use the main stamp set. It would be easy enough to stamp in Memento Tuxedo Black and colour it with Stampin’ Blends, but that was not the look I was after. I wanted a light and fluid watercolour look, but was not convinced that I could achieve it. But the day has come and I think I have cracked it.
