She said, "I figured out how to screen print, and I have like a little setup at home ," noting that the Cricut is popular among DIY creators online. After cutting the vinyl, she placed it on a screen , applied screen‑printing paint, and used a squeegee to transfer the design, adding a puff‑paste effect for texture.

Pun‑Laden Knicks Tees Cost $3 Each

The base shirts were inexpensive Gildan tees bought for $3 at Michaels, according to Alana. She used an orange craft paint called Speedball to create the bold lettering and added puns such as "Stevie Knicks," "Knickleback" and "Knicole Kimdan." The low‑cost materials allowed the group to produce multiple shirts for themselves and friends without breaking the bank.

Taylor Swift’s Text Sparked the DIY Project

Alana recounted receiving a direct text from Taylor Swift asking for a custom shirt, describing the moment as "my dream." Swift’s request prompted Alana to brainstorm the puns with the group, turning a simple fan‑request into a collaborative creative exercise. Alana also highlighted Mariska Hargitay’s enthusiasm, noting that the actress eagerly wore one of the shirts, which helped "bond" the group together.
