.......that there can be some slight enjoyment from receiving bills in window faced or security envelopes.
I have been introduced to the lovely patterns held within the envelopes and also the little 'windows'.
Great for adding into journals for added interest or as pockets, so you can tuck in photos and other bits & pieces. Here is one journal page that I have made - love the pattern on the left side.
On flickr you can find heaps of photos of other envelope patterns and also how some people have recycled them.
