I've used those colored carbon sheets for transferring patterns before - pretty straight forward. You just make sure the colored side faces the fabric. If you don't trust the steadiness of your hand, tape them down first. Make sure you are on a firm surface, like a table.
I've also used a iron-on ink but haven't seen it in years. you traced the wrong side of the pattern, then ironed it on. I think it was supposed to be good for quite a few times.
