And while I'm asking questions, do you have any recommendations for QSL card portfolios - notebooks for storing and displaying cards?
This place has a high review score on Eham. They supply the sleeves, you supply the 3 ring notebook.http://www.qslprotect.com/
There used to be a store that sold a notebook with "QSL Organizer" imprinted on the front, but I haven't seen it available in quite a while. In any case, any good 3 ring binder will do.
To display on walls try:http://www.hamstuff.com/QView/qslholders.html
I hope this helps.
