SUPER SIMPLE DO IT YOURSELF BACKGROUND STAMP

STRING STAMP

I think this photo is fairly self-explanatory but......  If you would like a simple background stamp, just wrap string around a block of some sort (I used the box which used to be packaging for a hole punch).  Tie it off at the top so that the knot doesn't intrude into the design,  Paint on a little acrylic paint and stamp it gently onto the surfact you want to decorate. Too much pressure tends to squeeze the paint out, so all you need is basically to make contact with the paper/card.
thats all there is to it.  Cheap as chips and quite effective!
