Seeds will germinate in just about anything as long as it holds soil and provides adequate drainage.
You can also use egg shells to germinate the seed but plan to take the plant out of the egg shell before final planting. Egg shells are tough and the roots can become trapped inside and never allow the plant to grow to full potential. For drainage, use a nail to poke several drainage holes in the bottom to prevent over-watering. Be sure to save the egg carton to hold the egg shells while the plant grows.
The cardboard roll found inside paper towel and toilet tissue is another idea. Cut the rolls into 2-3 inch sections, fill with potting soil and sow 1-3 seeds per container. The rolls can be planted just like peat pots without having to disturb the root ball of the plant, making sure all portions of the cardboard are planted below the soil surface. Any exposed cardboard edges will act like a wick and dry out the transplant - even if planted in moist ground.

Cardboard egg cartons work much the same way and are easy to use for germinating and growing seeds. Milk cartons, and juice boxes could be utilized also making sure to poke holes in the bottom for drainage.
After the seeds have germinated, you will need to provide adequate light for them. Then wait until seedlings are big enough to transplant to individual containers, cell packs or the garden.
