Instructables has a great Halloween thread. Its got a bit of everything too! Make up tutorials, cool decor tips, snacks, pumpkin carving. You won't regret it.
Brit+Co has really great tutorials on Halloween crafts and costume ideas. I've always liked how Brit+Co's team isn't super professional and glossy with their crafts. They look like anyone can, and has, done them.
So You Think You're Crafty (who once hosted BK in their competition) did a Halloween contest in their 17th season.
How About Orange's Halloween paper crafts are amazing. So cute and so versatile.
