Turn old newspaper into seedling pots. They can be planted directly into the ground as the paper will eventually biodegrade. You can form them by wrapping the paper around a jamjar or similar, or there are 'devices' that can be bought to make the pots.
These stained-clothespin planters are a super-cute way to display your herb collection—although they're best-suited for plants that work well in teensy containers, like rosemary or chives. Find the instructions at Stebbing House Design.
