Reading your thread was a bit of a "blast from the past" for me.
We also, in the past, stapled drapes at times. Most of the time it was just a cloth towel or two, and usually only when something else didn't work, and a drape moving would be "a bad thing"!!
Now-a-days, I can't remember when we have stapled a drape, the sticky drapes, and incision drapes, etc work so much better.
But yes, we used to do it too.
