hi luvthecommonwealth! Yes being cumbersome is an understatement.
Going for a world stamp collection is tiresome,
Until I got an idea 2 months back. It goes like this:
I stick all, including excesses, of a country's stamps onto a thick single std A4 paper, then insert that paper into a plastic sleeve, write the country name title for that sleeve, then put that plastic sleeve into a ring binder.
194 flags so that's 194 plastic sleeves, or about 4 binders! at 50 sleeves per binder, and I'm only on my 27th sleeve = 27th country!
still 167 country stamps to go!
