Today using a sharp knife I cut into the plastic lid from one of my sons old formula tins. I sliced a lengthwise rectangle (not very neat but it does the job) for him to post a giant set of playing cards into. He absolutely loves it!
Things to keep in mind:
- Knives are sharp so keep yourself safe by keeping the pointy edge away from your body.
- If you feel resistance (like I did) you may be hitting the inner metal lining. Just double check where the knife is landing and get back on track.
- Check there are no sharp edges your child can cut their little fingers on (this includes both metal and plastic).
- Have fun!
