I have a nice collection of magazines. I keep them stored above my stamping desk.
There is only 100 of them. I've only kept the ones I really LOVE.
As for Catalogs. I have almost all of the Stampin' Up! ones. Well from 2005 and up.
I keep them neatly in a file box that I made. And then look through them from time to time.
Close to my heart I only have 1 catalog
Other catalogs. From Companies no longer in business. I've recycled.
