Make your own DIY origami flower pots for seedlings from recycled newspapers. They make great biodegradable pots that can be planted with your seedlings.
Take a sheet of newspaper and cut it down the center. You only need one half of the page for each pot.
Fold the sheet in half bringing in either side of your rectangle (the sides that are furthest away from each other together).
Fold in half two more times, each time bringing in the sides that are furthest away from each other together just like you did the first time. (Flip and fold in the same direction as before.)The third fold is made only to crease the paper, so unfold it again once you have marked the paper.
Take ahold of the top fold on one side of the paper and press it open and down. You should form a triangular shape at the top.
Flip the paper over and repeat on the other side.
Flip the sections by rotating the top and bottom sections in the same direction. You should end up with smooth sections on the top and the bottom.
Fold both outside edges in towards the center seam. Flip and repeat on the other side.
Fold the outside edges in towards the center again and repeat on the other side.
Your pot is basically finished!
To keep if from falling apart, fold the top edges of the paper down towards the point.
Open the pot as you would open a folded paper bag. You can now fill the pot with soil.
You can store them easily in a space efficient way by folding them back up again and filling an open pot with several folded ones.

Notes
You can leave the flaps as they are or tuck them inside the pot. I find that the pots are more stable if you leave the tabs on the outside.Press several pots together to hold the tabs down between the pots.If you want to make a bigger pot, use a full newspaper sheet. It will be less strong, but you can use two sheets of paper together to strengthen the pot. Using several layers will make for a stronger pot, but it may impede the root growth and speed at which the pots can biodegrade in the garden.
