I got two stars. I was never able to get stability even when it seemed like my cakes were perfectly tiered, stable, got all the others checked. But I couldn’t ever figure out how to get stability.
Did you use whole pieces or did bits fall off the ends during construction? I added this line to the main page half-way through last week:
Cakes are expected to be centered on the cake stand and stable made of complete whole pieces that aren't too far spread apart.
