I will never forget when Sean and I owned our first house.  Jane and Jerry agreed to help us hang wallpaper in the kitchen.  Jerry was a pro!  They came over on a Saturday and the project began.  As the day moved into evening, Jerry was still pasting this plaid design.  By midnight, we were all ready for bed, but not Jerry.  He was determined to hang it perfectly.  When it was done, you could not tell where one piece started and another stopped.  He was meticulous.
