What are the functions of the front and back sides of the Time-Folding Cloth?

Hah, talking about the Time-Flying Cloth, this is one of my favorite gadgets! Its function is actually quite straightforward—it all depends on which side you use to cover an object.

Simply put, it's like a magical fabric that can make items "rejuvenate" or "age rapidly."

Rewind Time for Renewal (Front / Clock-Patterned Side)

This side is the Time-Flying Cloth's main feature, usually red with a large clock pattern.

Function: When you wrap an item with the clock-patterned side facing inward, the item's time rewinds, restoring it to a previous state.
Real-life examples:
- Fix broken items: A shattered vase wrapped this way will become intact again after a while.
- Restore old items: A tattered comic book becomes as good as new, like it was just bought from the store.
- Refresh food: Stale cake regains its freshly baked flavor.

Easy reminder: Clock side inward = Renew, Rejuvenate, Restore

Fast-Forward Time for Aging (Back / Plain Side)

This is the reverse side, typically blue and plain without patterns.

Function: When you wrap an item with the plain side facing inward, the item's time fast-forwards, aging it rapidly.
Real-life examples:
- Accelerate growth: Wrap a seed, and it may sprout and bear fruit within minutes.
- Age objects: A brand-new robot toy becomes rusty, resembling an antique.
- Cause damage (as Nobita often does): Accidentally covering a new item with this side might turn it into a "historical relic" or even reduce it to dust.

Easy reminder: Plain side inward = Age, Decay, Deteriorate

Summary

The key to using the Time-Flying Cloth lies in which side touches the object.

To restore an item, use the clock-patterned side.
To fast-forward an item, use the plain side.

Never mix them up! Otherwise, like Nobita, you might accidentally make a broken toy "age to death" instead of fixing it—leaving you utterly heartbroken!
