Hi Pat. I cut holes lengthwise all the time in blue foam. I get snug fitting holes using a hot wire setup. I do not know how many ar interested but I took pictures wondering if people want to see how it is done? The method is quite adaptable, as if can be used for channels, and any shape you can make of wire. Should I put it on my web site??
