if you do a lot of fusible do what I do..I do use a teflon pressing sheet..just a cheap generic one, that works really well..but often we are in a hurry and might forget it..so I bought a cheap, but decent black & decker iron at a thrift shot for $3.00...it gets really hot, has steam so I can still do steam a seam, and if it should be ruined, no big deal...but at least I am not ruining my Maytag cordless that can't be replaced!
