Cards Stuck to Envelopes

[debodun]

I have bunch of nice greeting cards, but the envelope flaps are stuck to the cards. I already tried the freezer and microwave methods to no success. I am afraid direct steam would wrinkle them. Is there any other way to un-stick them?

Nope.

From "Helpful Hints from Heloise": try ironing them, no steam.

If anything works, that should. .. but not HOT iron ..
