In search of missing pieces

What do you do when you're missing a creamer? You substitute a cute Santa Claus tea figurine (thank you, Linda!), that's what! He's filling in admirably, I think, in light of the missing piece that I was unsuccessful at locating in 2016, so I'm hoping for better luck with the search in 2017.
Last year I bought this Christmas chintz teapot and two-tiered serving tray at a T.J. Maxx, and after I blogged about it, my friend Joy thoughtfully located three dessert plates and the sugar bowl for me—on clearance! As you can see, my table setting is a plate, four teacups, and one creamer short of completion. When I started seriously looking for the missing pieces in the fall, I was very surprised to find I could not locate the missing plate at any price, anywhere. Not even at Replacements.com, which told me that there must not be many of these out there! I could buy the sugar and creamer as a set, but I don't *need* another sugar bowl, so … I'm holding out.
What do you think about mixing this Christmas chintz pattern? When my dad gave me money to buy my Christmas gifts from him this year, I bought two of these pretty teacups when I found them at Marshalls, and I'm thinking they could blend well. Or would you just mix and match with four different patterns of Christmas teacup? No rush, though. I won't be putting these out again for another year!
