Traumatic Tiered Cake Experience

As a pseudo beginner cake decorator (I've been at it for about a year now), I had to at some point take on the challenge of a tiered cake. And I must say...this cake was a challenge. I created this spiderman cake for a kid's birthday party and unfortunately, kids and fondant don't mix...they just dont really like it and I can't say I blame them. Sooo frosting it was, and so I was already out of my "just cover it up with some fondant" comfort zone. I made some big time rookie mistakes with this cake, but I guess you've got to start somewhere. I did a good deal of research on how best to create tiered cakes so I knew enough to put dowels in the bottom layer in order to hold the weight BUT my bottom cake was not as level as it should have been. And, to make things easier during the party, I had the top tier on a cake circle but because the second layer was uneven...the top layer was tittering on top and I had about a half centimeter gap of space between the two cakes...YIKES! So I created a night yellow band to cover up this unsightly space and drew some frosting spiders on it. Lesson learned, make sure your bottom cake is level, you can imagine how frightening that car ride was for me. But I must say, the cake was delivered to a very excited Spiderman fan birthday boy.
