From this Gemara we see two important concepts of the Mitzva of writing your own Torah.
1) you are supposed to use it, be it for learning or just for Krias Hatorah. It is not supposed to be a relic locked inside a safe.
2) it's commendable to beautify it as much as a person can, so others will see it and appreciate it. This is often called in Halacha זה קלי ואנוויהו.
