Curate, connect, and discover
Headcannon that C!Tommy learned to knit and / or crochet from both Phil and Techno when they would take time to sit down and make little silly things like scarves and stuff. Tommy then went on to use this as a coping mechanism, so now whenever he is stressed, he makes something and then tosses it into a closet chalked full of a bunch of other things he's knitted.
Also, he's made everyone in the server (which he trusts or thinks is cool) something to wear.
Wilbur has only a small friendship bracelet from Tommy because knowing Wilbur, he wouldn't take the sentiment seriously and would just brush it off- that and Tommy doesn't fully trust Wilbur
Tubbo has a yellow cardigan that took Tommy a total of two days full of nonstop knitting.
Phil has a bucket hat (which took Tommy a while to figure out because of how its structured.)
Techno has a crochet apple.
And so on.
