Love the muffin tin idea! I have PLENTY of those, and I can make a good case to Darlin that I can use some of them in the garden and not soil them with good clean soil! I like the idea of having the seedling in a situation in which it would be easy to peel off the container or pierce it so its little toes can get out!
Mine are actually the plastic containers, so no worries from anyone about using them.LOL
