We have a large (12ft x 8ft) rug in our living room,
on top of a carpet.
The rug keeps getting rumpled up,
mainly along an old fold in the rug.

Is there any simple way of holding the rug down on the carpet?
The only thing I can think of is a nail through both
onto the wooden floor underneath.

There are expensive backing sheets you can buy, but with no guarantee even
they would work, I found a simple solution.
Get some wool about the same colour as the border of your rug and tack
stitch the 'trailing' edge to the carpet with a bodkin. You only need about
one 3/4 inch stitch every 3 or 4 inches or so. After years of constantly
turning the rug and carpet to try and find a combination that didn't creep,
the rug has remained in place for a couple of years now and nobody notices
the tack stitches. Obviously, if yours is a fitted carpet you may find the
stitching more difficult than I did with a non fitted one, but it would be
relatively easy to make a curved bodkin and hook it through with pliers.
Simple, effective, and costs next to nothing.
