Welcome! I'm still churning out a few Christmas cards now and then--we're down to the wire for sure! In fact, from the small batch I took in to the post office today, I was told that one envelope won't make it until the 26th. I still got more cards out on time this year than I have for the past couple of years, so I'm okay with that.
I've found myself leaning on the MFT Stamps Hand-Lettered Christmas stamp set this year, mostly because it's quick and packs a nice visual punch, whether embossed or inked in multiple colors. I also used the Stars Above stamp set set and coordinating Die-namics quite a bit this year. I paired Hand-Lettered Christmas with the Moroccan Lattice Background for the card on the left.
I'm working on a couple of projects that I'm still hoping to share in the next few days, but that depends upon time management. . . or lack thereof, obviously. ;-) May you have a lovely Christmas season!
