Reply Stacked Pillow Cake - Level of difficulty?

Sarah ...

Well this is kind of late, but thank you all SOOOOOO much for all of your advice!!! I printed out a coupon and went right to Michael’s to get those pans (Thanks Pam, Nina & CorpseQueen), and I heeded the advice of Judi and P&N and just added the amount of cake mix I felt was appropriate (not that crazy amount they have on the packaging) and they worked wonderfully!!! I did carve them a tiny bit to get more definition, but other than that, it was great! Thank you so much for your help and giving me a boost of confidence before I jumped into this cake adventure! :)
