Not really, my main focus has always been mastering recipes and making money. I've got a layout that I rarely change and I'm super happy with. Although for some reason I love to expand my bakery!
My last big decoration change was Halloween when I added a corner to my bakery. I do with that so many of the Halloween Decorations weren't huge. Maybe I'll get my bakery big enough that I'll have room for more. But first is always the reindeer!
