I see a lot of people have made block cakes, and there are a lot of comments about how difficult it was... can anyone give me any pointers, suggestions, tips to make my endeavor easier? I would love to hear anything that you have to say.
I can give you advice on what not to do 
I made a stacked block cake...(one of my first cakes)...it was two blocks on bottom with one stacked on top ...I didn't dowel it and it kind of sunk in, fell & took some of the bottom block with it...total disaster!!
So I guess my advice is to use a sturdy recipe and using dowels if you are stacking them 
hi i made a few. mine were baby shower cakes but i did not stack them atop each other. i put two on each board on one and on another i put each one on separate boards. that way they could move them around the party. they had alot of food for that one. i have pics of them both in my photos. hth 
You need to put each block on it's own board, and you can stack them, just be sure to dowel each corner. They're not hard, but takes a little time to do each one. I have some in my pics.
I have made blocks I think 3 times now. I make a 9x13, split down the middle the long way, and then cut in thirds the short way. I frost middle with buttercream, stack, then freeze. If you are cutting your blocks, you definately have to freeze so you can frost the blocks. Also, I have stacked them without a problem. I just put straws underneath the stacked one. ( I used the straws as dowels.)I have not stacked more than one. I have made 3 blocks at a time, and I thought it was kinda fun, but if you look in my pictures, you'll see I made 6 of them for a baby shower, and I was so tired of them by the time I finished those!! Good luck, they're fun in moderation!
