In the past all my wedding cakes have been for close friends & family so I can stack the top tiers & finish details at the reception, but tomorrow I'm wanting to take care finished.

It's a 3 tier round -- 14, 10, & 6. I'm using Wilton wooden dowels -- 5 in 14, 4 in 10. I don't have a long enough dowel to put down the middle of all, so I have one going down the center of the 14 & 10. I'm contemplating putting another down the middle of the 10 & 6. Any advice?

Should I be okay or do I need to just stack the 6 at the reception?

I wouldn't add another center dowel. I think it will be fine. Actually I don't always put a center dowel in my cakes and I've never lost one yet. If it makes you feel better you could add the 6" at the venue.

Thanks for the response. I ended up putting another dowel and may not have needed it. The cake made it fine! *whew* I was a bit worried too about my buttercream melting in hot humid south GA weather, but all was well.
