One of the best things about decorating for Halloween is that there are no rules. Really! And that especially applies to pumpkins.
I've gotten quite a few questions on the best way to decorate pumpkins.... and I always tell my Halloweenies.... "Whatever you love, is the best way to do it!"
Add paint or fabric, cut outs or jewels.... whatever makes you smile and say "That's a fab-boo-lous pumpkin!" works for me!
