What else do you need? We also went to our nursery and picked out a few seed packets and grabbed a small bag of sterile seed starting soil.
To get started, I cut apart the egg carton bottom and top. We'll be planting in the bottom, and the top will make a good tray for catching drips and spills from watering.
Look at all those hopeful sprouts! In case you are comparing, these are tomato seedlings, and the seeds show above are squash seeds.
*On 'awesome mom' points. I don't want anyone to think you have to do silly crafts with cardboard egg cartons or toilet paper rolls with your kids to earn awesome mom points. You should give yourself points each time you spend time with them, care for them, listen to them, and love them. See, you already have a perfect score :)
