Not sure if this is new to anyone but myself. but the other day i was doing my usual walmart hunt for junk and ended up in the arts & crafty section . i found these flat heavy plastic cards that are used to spool needle point thread on. shaped like a fat letter I . 50 for $1.49 . i spooled almost 50 ft of spider wire on one and they fit perfectly in my little altoid tin fishing kit. the one with the sliding top. anyone else ever use these things ..there great!!
