I don't find these cards easy to make and have found the easiest thing to do is to stamp directly onto the card and make it a one layer card.
I'm on a mission this year to use stamps that I haven't got inky yet or have rarely used. I got this sweet frog from Penny Black end of last year so it was my first choice for this card. The sentiment is also from Penny Black and I coloured the images with Promarkers.
I then made two cards for the Christmas challenge using another Penny Black stamp from T for Transparent set 'Christmas Friends'.
I added a little bit of Icicle Stickles for a bit of sparkle.
