My husband had a big mailing going out on behalf of a fraternal organization of which he is treasurer. The mailing featured a card that had each member's address printed on it and that information needed to show through the window in the envelope he would be using for the mailing. SInce he'd already checked the window envelopes he had from a previous mailing and discovered that the window in those envelopes was *not* in exactly the right place for *this* mailing it seemed like this was going to end up being the kind of challenge we simply don't need these days you know? But there is a "happily ever after" ending to this story: I went to Staples with a sample of the card - and much like the handsome prince in Cinderella I "tried on" envelopes until I found the *one* the fit. at that moment the skies turned blue and the cute fat little birds started singing and I could hear the violins swelling and the waltz music starting as I walked toward the checkout. Staples you're my dream...place to buy #10 envelopes with weirdly positioned windows!!
