Just saw this post on Wal-Mart mag. firestarters & thoght it ironic. Last week I was in there & picked up a $1 pack of pressed waxed sawdust firestarters from the Sporting Goods section & then found a $1 pack of fatwood in the section that has fireplace accessories.
Cut them each into three inch sections & made a firestarting sandwich. Laid the pressed sawdust bar down first, since it's flat on all sides, laid a layer of 100% cotton balls on top of that, & then laid a section of fatwood on top of the cotton.
Tucked in the cotton balls on all sides to make it neater & then secured each end tightly with waxed dental floss. Vacuum packed to stay dry; they weigh next to nothing.
Slice open the plastic, puff up some cotton from the middle, hit it with sparks from a ferro rod, & there you go.
