OK, so here's what I tried....so far:
Light ironing.
Deciding not to (yet) work "moisture" into the equation, I put the blanket between two white sheets, made sure it was flattened & stretched out, then ironed lightly over the blanket several times. I had the iron on the lowest heat setting, and only ironed for about 7-10 seconds at a time.
The result?? Better, but still some wrinkling (see pics below). Any further advice? Should I try a very light spray of moisture? Leave it alone? Burn it in a ritual to excise Gandil's sins?
I forgot to take "before" pics (duh), but here are the "after" pics. (make sure to look at the last few, where I get down to "eye level" and with no flash. That is where you can see the wrinkles that still exist.)
***I should note for the record that the light staining/soiling was already present. The ironing did not do anything to alter the color/brightness/condition**
