Here's how we made our oyster bags:
Step 1: Fold the mesh to make a box shape
Step 2: Cut the 4 corners on each side so you can fold to make a box shape
Step 3: Use zip ties to secure each end
Step 4: Cut a flap so you can access the oysters
Step 5: Attach the plastic floats to the side using zip ties
Step 6: Repeat
Step 7: Test it!
