I collect Great Britain and Israel and have lots of swaps if you or a friend are interested.
To get started yourself, I advise specialising. Having a nice album to put them in is pleasing. You can buy a ready made one from Stanley Gibbons, or create your own if you have a printer and wish to save money: visit Ebay and search for 'print your own stamp album'. I bought the Great Britain CD and am pleased with it.
Older stamps are best left on envelopes. They may be worth something.
