I sell Usborne Children's Books rather than CM, but some of the same advice goes for all home party businesses. Here's what people have told me so far. -
Look for craft fairs or that sort of thing. You can set up a table to sell stuff and, most people say more importantly, make contacts for parties.
"Donate" extra catalogs to your doctor's and dentist's office magazine racks (ask the secretary first.) Make sure to stick in several copies of your contact information or web site.
Offer specialty parties - in your case, maybe geared to teens, grandparents, etc.
Best of luck with your new business!
