KerrieD: "I was thinking of gluing some water bottle caps to the bottom of my foamcore board..."
Howdy! I've been trying to concoct a disposable system of pillars and separator plates since I'm an addicted newbie and give away all my practice cakes. Since I want to practice on tiered cakes, I don't want the cost or hassle of having pieces returned.
Haven't tried my "system" yet, but, after trying lots of lids/dowels/etc., found out that Costco has cardboard "slip sheets" for free, 4'x4' flat cardboard that fits between layers on pallets--just ask in the back of the store. Crystal Geyser Natural Alpine Spring Water, California, 8 FL OZ 240 ml size has a lid with an inner ring that perfectly accepts the Wilton "4 Plastic Dowel Rods" (4 - 12.5 in Long) package. The only cost here is the Wilton Plastic Dowel Rods (I always use a coupon), and the initial cost of the water, which I'll drink anyway and recycle the bottle. Was planning on using lids from other water bottles as "feet" on the cakeboard.
That way, I can make/practice/give away tiered cakes with a support system that is almost free. Since I'll be bringing the free cakes anyway, I'll just set up on the "tiers" at delivery, then they'll take off the top layer as the cake is cut and each layer will also have feet!
Has anyone else got a "home-made, cheap" tier/separator plate "system"?
