you could always learn to skate without a stomp pad on - it will make you better.
To the OP, you're asking something difficult, since you don't want to advertise. Most people get stickers of the board, bindings, outerwear, goggle makers and put them on their board creatively. I've seen energy drink stickers on peoples boards too (which makes me laugh). There are online guides (google search it). Don't put Burton stickers on your DC board etc, and don't have them all centered.
You can buy stickers from snowboard shops, or buy them off guys on forums who make die-cuts. Pm me if you can't find anyone. Or you can send sase to companies asking for free stickers.
