Joy: I cut a 4x6 pocket card, trimmed it for a A2 card, rounded the corners and added washi tape and silver shimmer trim. The gold polka-dot washi tape is actually not that wide, but I taped 2 strips and lined up the dots...

Noel: I changed the size of the pocket card on Cricut Craft Room (I have a E2) to fit the A2 card, added the washi tapes and gemstones, then added some glitter gel.

Tree: This one was a "little" more time consuming...Artfully Sent cut out the tree/banner design for me. I layered woodgrain washi tape on a piece of 5x7 cardstock and adhere behind the front panel (for the trunk cut out). Using the leftover leaves cut outs, I taped different washi tapes, trimmed and adhered them on. For the smaller leaves, I adhered and colored them with watercolored pencils. 

I also added gold polka-dot washi tape for the banner and adhered them on.

Of course, to make your life easier, you could have taped washi tape on cardstock and cut them with the Cricut...but I decided to save some cardstock and washi tape...
