I've done this a lot of times (candles, carpet, other fabrics). Place a brown paper grocery bag (just one layer of paper) over the stained area and iron it with your iron set to the highest setting. The paper will pick up the wax instantly and become see-thru, as if it were saturated with grease.

Repeat.

Each time you do it, the wax stain in the paper gets a bit smaller. When the paper is clean... you're done.
