Step 1: Supplies & Tools
1. Toilet paper / paper towel cardboard tubes. ( How many you need will depend on the size of the pan, I needed 28)
2. Baking pan: This can be metal or glass. If you can find one at a sale for a few cents then that's even better. The one in the pictures was bought at a dollar shop. So I invested a whole dollar + tax so far.
3. Growth medium. If you have it then use a good, fine compost. If you do not have a medium you will have to buy one. Which costs more money. Or get creative (feel free to share your creative solution to getting soil)
Step 2: Flatten Tubes
To do this step flatten each tube so that it forms two distinct edges or creases. Next open back up the tube and center these creases on each other. Now flatten again forming another set of creases. After fully forming the creases open the tube again. The tube should be mostly rectangular now and have four distinct corners. Do this with all of the tubes you will need.
