No one will dare darken your doorstep while this aging, spider-infested wreath hangs over it.
The secret is reindeer moss, actually a lichen, available at crafts stores and garden centers.
The natural color of the moss, combined with some creepy-crawly embellishments, will make it appear as though you pulled the wreath from the depths of a cobweb-covered attic.
How-To
1. Hot-glue handfuls of moss to a Styrofoam wreath form until covered.
2. Apply a thin coat of craft glue to plastic spiders (available at Halloween stores); sprinkle with black glitter. Hot-glue spiders onto wreath.
3. Hang wreath using monofilament.

I can't say enough good things about this wreath! The supplies were easy to find and inexpensive. It was also easy to do and fun to make with my 2 year old. I have gotten so many compliments on it especially from our mailman.
I live in CA as well. I found mine at Michaels Craft store in the floral section. about $4.99 a bag.
love the wreath -- cant find white reindeer moss ANYWHERE. Help! I live in CA, but I can order online. Thanks.
