"The most important part of Christmas!"
I have used Gripping Stuff every Christmas since I first discovered it, some years ago, and it has saved so much frustration from trying to find ways of displaying cards clearly and in our restricted space. I have never had any problem with it sticking to walls (even though out house is old and these are uneven) and keeping all our cards displayed throughout Advent right up to Twelfth Night. New Gripping stuff is one of the first items of Christmas shopping each year - and then I roll it back up and keep it to reuse for birthday cards during the year, too.
