We should make some!
we have to my knowledge 8 rolls of blue foam floating about and it is all Haven's (well technically the boffer club's but whatever) and since we will have a space to store them in Ian's or my house (until we get a spot on campus) I think this is a good idea.
however my more pressing question is this. should we try to do anything special to the loaners to make it clear that they are loaners? my idea was white electrical tape on the handle with red/green/blue tape marking the class.
