I am trying to use some of the retiring colours, so I pulled out Bravo Burgundy (can't remember the last time I used this!), More Mustard and River Rock (not going to miss this one, lol). For the centre image I used a stamp from the Lovely as a Tree set. I quite like the result so I think this will be one of the cards for my next class.
And, just in case you are curious, this is the other card I made; this one is not for any challenges.
