I read a post some time ago about using clear (I guess) placemats from the Dollar Store or out of the craft section at cloth stores. I think they are technically used to decorate but they make sturdy templates. I intend to find some if I can keep my CRS from kicking in when I am in the store. But as everyone said you don't need a lot of rulers. Decide on which rulers you think are the most important for you and buy them gradually as your money permits. Don't forget coupons, sales, thrift stores and asking for them for presents (or gift cards to your favorite store).
