I was actually thinking of stopping by ikea on saturday to look at those, i haven't actually seen any made out of that material. Do you happen to have pictures, or a link to somebody that used the cuting boards.
I started the Ikea Cutting board project but havnt finished it yet because im unsure of where the holes need to be drilled. Chalk it up to laziness though - ive had this project 'on the go' for months.
The cutting boards are obvious: they are in with the regular cutting board stuff. Everything other than what you need is either 1/4" thick (solid plastic - you dont want these) or made of wood. They are usually kept in a big open box for people to dig through.
be warned: 1 pack of cutting boards has 4 boards in it. 2 are black 2 are semi transparent. so if you want a full set of black boards, you need to buy 2 packs of cutting boards. Luckily they were only like 8 bux each or something though!
Canadian tire has clips/bolts for mounting hardware just FYI.
