I have a 12",9",6" for tomorrow. 50th wedding anniversary. I only have 8" and 6" SPS plates. Can I use the 8" plate with the 9" tier or do I need to alter my design to 12", 8", 6"? This would bring me under the 100 servings they asked for.
I have never used SPS so I do not have an answer. I am sure someone here will be able to tell you. If you can not use the 8 inch SPS plate with the 9 inch cake you could always do a swirl rose bouquet for the extra amount of cake. They are very beautiful. Here is a link where they show a tutorial. Just an idea in case you need more cake. They are very popular these days. Others may have a better solution. Good luck!!
AThose plates are fine. I've used them. The difference is very small & the columns will still support everything.
