I think the best way with this challenge is to choose some supplies and make all 6 cards in a similar vein.
So this month I've used the remnants of an Authentique christmas paper pad.....green,red and gold card........red twine......some stamped images left from last christmas.....washi tape......and finally added one embellishment.
the first 4 cards are all A6 size
the washi tape used instead of a sentiment saved a lot of time
I'm not quite sure why I'd stamped one in red.....but I think it works okay
the final 2 cards are square and I decided not to add twine.......but a larger embellishment
here's all 6
So 12 christmas cards made now......only about another 30 to go!!!
