I'm trying to build a prototype of my game from the September GDS, "I'm Waiting!" (http://www.bgdf.com/forum/game-design/game-design-showdown/gds-september...) to playtest in March and am having trouble finding cheap, soft, and aerodynamic ~.75x.75x.75 foot cubes that I can purchase. Ideally I would purchase cheap ~.75x.75.75 foot food-shaped foam, but I get the impression that finding that for cheap online is even less likely.
The best pricing I've come across for large but soft material cubes is a $20 inflatable jumbo dice set of 6. I'm looking to buy 40 or 50 cubes, so $20 per 6 is incredibly expensive. This pricing is making me heavily consider substantially lowering the game's cube count.
Does anyone know of any cheaper sources for large and soft cubes (or, more ideally, food-shapes)? Does anyone know how I would be able to go about making my own soft cubes or food-shapes and roughly how much making them myself would cost? I understand that foam may be an option for making the cubes myself but I do not understand how to go about making cubes or food shapes out of foam and am interested in hearing if there are any other good options. In terms of purchasing cubes: Different colors would be preferred, but the color of purchased cubes is a non-issue (I can use spray paint).
Thanks for the advice so far, guys. I hadn't thought of looking into floral cubes, and a quick search found a good size and price for me. http://www.marshallfloralproducts.com/11-03260--OASIS-4-Cube--case-of-36...
With some changes to the game rules, I've been able to set my cube requirements to P^2, where P is the number of players. For starters I'm looking to test with no more than 6 players, so 36 is a perfect number. In terms of size: These cubes need to be big enough to be difficult to balance many of them on a tray and to be easy enough to throw towards an opponents' tray to knock off cubes. 2 inches is not a good size for this, but 4 inches may possibly work (though I would prefer larger). This particular site offers 48 5 inch cubes for ~$40, which is a bit more than I would like to spend and gives me more cubes than I need, so I'm heavily considering trying out the 4 inch cubes because they come in a ~$20 pack of 36. It'd be nice to feel the product before buying a bunch, though, so I'm going to try and see what local educational and art stores I may be able to buy these sorts of cubes at.
