-Two plastic bottles of the same size
-A Zipper (the size depends on the thickness of the bottle) preferably red or similar
-Sticker paper (for eyes)
-A pencil and a marker
And we are ready to start!
Step 1: Prepare bottles
Repeat this with the other bottle.
Step 2: Paste the pieces
Now join the pieces. Paste the zipper with one bottle (carefully) and then with the other bottle (it will cost a bit more).
For the eyes, draw two ellipses in the sticker paper (the size you want) and cut them out. Draw a black circle as a pupil with a mark and paste it into the bottle.
Leave a few hours without touching the monster. So contact glue dry completely.
Step 3: Finish!
You can use it as a piggy bank, as a container of things (or double container) or merely decorative (which is very nice =])
