For a holiday like Halloween, Pinterest excels.
Once you sign up for a free account you can search to your heart's content and see other user's pins on Halloween decor, party snacks, and, of course, costumes.
Try searching with different key words for the most results, like clever costumes, DIY costumes, handmade, kids, etcetera.
And not to overwhelm you, but there are already a few hundred million pins all relating to this topic.
For a silly and creepy Halloween mask, check out www.freakmasks.com.
You submit a photo of anything, like, your best friend's face, and for $25 bucks the website will turn it into a fabric mask.
And finally, turn your tag into the spookiest decorations on the block.
For example, hide your cell phone into a pumpkin on the porch.
Call it from another phone, put the call on speaker, and when the kids ring the doorbell, haunt them with scary voices.
Or download eyeball videos or beating heart videos onto your tablets and hang them in windows looking out onto the street.
