Hi, y'all.
 
Does anyone recall a previous posting some time back that outlines  how to 
iron out a crinkled tape?  I'm sure I saved it, but with upmteen  listings saved 
over the years in two different computers, it would probably take  the whole 
3-day weekend to find it, and it's just easier to ask  again.
