It is funny that you mention this...I orginally freezed mine because that is what I read to do, but didn't realize it was for the harder waxes, so that is why I was having such a hard time cutting my wax! And yes, the plastic pulls right off when you freeze it, BUT it is near impossible to cut until it thaws out... Once it DID thaw, I just cut it with a large knife (soooo easy!). I laid it on the counter with an overhang and cut from that overhang. I am actually only cutting small amounts off though, so for a large scale, I'd say the wire thing is best!
