אורח חיים ח׳Orach Chayim 8

Se’if 1א׳

יִתְעַטֵּף בְּצִיצִית וִיבָרֵךְ מְעֻמָּד.

He shall wrap himself in a fringed garment and make the blessing over it while standing up.

Se’if 2ב׳

יְסַדֵּר עֲטִיפָתוֹ כְּדֶרֶךְ בְּנֵי אָדָם שֶׁמִּתְכַּסִים בִּכְסוּתָן וְעוֹסְקִים בִּמְלַאכְתָּם פְּעָמִים בְּכִסוּי הָרֹאשׁ, פְּעָמִים בְּגִלּוּי הָרֹאשׁ, וְנָכוֹן שֶׁיְּכַסֶה רֹאשׁוֹ בְּטַלִּית.

The order of wrapping is like the way that a person covers his head for work. Sometimes his head is covered and sometimes his head is exposed. And it is correct to cover the head with the fringed garment.

Se’if 3ג׳

טַלִּיתוֹת קְטַנִּים שֶׁלָּנוּ שֶׁאָנוּ נוֹהֲגִים לִלְבֹּשׁ, אַף עַל פִּי שֶׁאֵין בָּהֶם עִטּוּף, יוֹצְאִים בָּהֶם יְדֵי חוֹבַת צִיצִית, וְטוֹב לְהַנִּיחַ אוֹתוֹ עַל רֹאשׁוֹ רָחְבּוֹ לְקוֹמָתוֹ, וּלְהִתְעַטֵּף בּוֹ, וְיַעֲמֹד כָּךְ מְעֻטָּף לְפָחוֹת כְּדֵי הִלּוּךְ ד' אַמּוֹת, וְאַחַר כָּךְ יִמְשְׁכֶנּוּ מֵעַל רֹאשׁוֹ, וְיִלְבְּשֶׁנּוּ.

Small fringed garments (talit katan) of ours that are customarily worn, even though they are not wrapped, they fulfill our obligation for fringes. And it is good that one places it over one's head, the long way, and wrap it. He should stand this way wrapped for at least the amount of time it would take to walk four cubits. After this he can pull it over his head and wear it normally.
