For those that have a keezer and build collars, has anyone that has not re-used the lid and just built a wood topper to match the collar have any issues with insulation? Would a few inches of foam do the trick? I ordered my 7.0cf GE freezer from HD when it was on sale for 159.99 with free shipping. Should be here on the 27th and just trying to figure out what I'm doing with it. Collar for sure, but I'm undecided on the top. I've seen some lids being used that look good, then others that look totally out of place. I'm not going to do anything like a coffin top or anything as my wood working skills are next to none. I was just thinking about doing a simple wood top to stain and match the collar. Any thoughts/suggestions?
