Hiddur Mitzvah - הידור מצוה

This is my G-d and I shall glorify them.

“This is my G-d and I will glorify them.” The Sages interpreted this to be linguistically related to beauty, and interpreted the verse: Beautify yourself before G-d in mitzvot. Even if one fulfills the mitzva by performing it simply, it is nonetheless proper to perform the mitzva as beautifully as possible.

Make before G-d a beautiful sukka, a beautiful lulav, a beautiful shofar, beautiful ritual fringes, beautiful parchment for a Torah scroll, and write in it in G-d's name in beautiful ink, with a beautiful quill by an expert scribe, and wrap the scroll in beautiful silk fabric.

We learned: A lulav that has three handbreadths in length, so you can wave it. This indicates that if the lulav is less than the measure, it is not fit. Rather, it is a lulav has no maximum measure, but it does have a minimum measure. So too, ritual fringes have no maximum measure, but they have a minimum measure.
