To start, turn the duvet cover inside out so the ties at the top corners are exposed.
Next, take the loops at each corner of your insert and tie them to respective ties on the duvet cover.
After that’s taken care of, fit the duvet cover over your insert like you would a pillowcase over a big pillow — make sure everything lines up nicely!
And last but not least, neaten up any excess fabric around the bottom edge then button it, zip it, or tie it closed depending on how your particular cover works best.

Fact

Brushing your teeth too hard is bad for you.

Doing so can wear down the enamel. This would then make your teeth sensitive to hot and cold foods. Brushing too hard can also damage your gums and teeth in the long run.
