Step 2: Pop the Top & Cut it Open
Start by cutting off the top of the Soymilk carton.
Open the top of carton.
Then cut along the left edge, so the Silk Soymilk logo is located to the right of the cut.
Then cut off the bottom the carton.
You should now have two parts, a flat Soymilk carton and a little square thing. (The square things work well as seed planters too.)
Step 3: Dry the Inside of the Carton
Using a paper towel or rag, throughly dry the inside of the carton. Clean off any remaining Soymilk.
Step 4: Prepare the Cap
Cut the top panel entirely off. Be sure to cut along the fold.
Then carefully cut the cap out of the top panel.
