I have only used dowels and don't want risk it on my next cake after all I have read about stacking and the problems. I don't have time to order a proper video to show me how...if I had the time I would!
What is the best way to stacking system my three square book cake?
If you don't have time to order the sps system, then I would definately use the dowels like you are "used" to useing.
I made a cake this weekend with a 10" & 8" squares and a 6" round. I used square cake boards under the square and a round sps under that cake and it worked fine.
Here are the instructions http://www.cakecentral.com/cake-decorating-ftopict-603925.html
I use the Wilton hollow hidden columns with the smooth separater plates.
Thanks for the info
SPS does come in square as well as heart shaped (I keep begging them for hexagon shaped)
Where would I find the square sps?
I order it directly from bakery crafts, but I am sure you can get it from where ever you buy the round...
I ordered my SPS plates from www.LarksCakeAndCandy.com which is a sister store to www.OasisSupply.com, but Lark's doesn't have a minimum order like Oasis.
