I nearly forgot about this one too. I did a demonstration recently and this was the card I demonstrated.
I made it using the tree stamp from the Forever Young set.
I firstly cover the tree with the more mustard markers and then using a selection of autumn coloured markers sploged colour in different area and then finally used the chocolate chip marker to colour the trunk and the brances (and the swing). Not sure if you can actually see the effect of the colours in this photograph but it does look effective IRL. The ribbon is the new dotted scallop ribbon and the sentiment is punched out with the word window punch.
