Reply to "how to carve pink foam"

For cutting 2" thick foam board; I use a Olfa knife with break away blade points. I bought mine in Home Depot, you can find them with the wallpapering tools. They sell the replacement blade packs with standard, and a thicker heavy duty blade, get a pack of the sturdier heavy duty blades. You can extend the blade out about 3 inches or so, with a fresh blade, and make a clean cut in foam board. Mine is the nicer knife with the black and yellow handle, and the blunt blade on opposite end for prying open can lids. I carry mine with me all the time. They are inexpensive.
