Lovely isn't it? I think that's on my hit list for the NEC show in March...... I love their secret garden gate as well. It started off as a bit of a problem session for me, I wasn't happy with anything I started to do. In the end, my mistakes made the browny yellowy backgrounds for these ATCs and a couple more.
