Gift ideas for niece who’s into sewing?

Hey there, I’m an uncle to a soon to be 15 year old niece who recently got into sewing and has a starter sewing machine. (Hope it’s ok that I post here!)

I want to get her something for her birthday next weekend that has to do with sewing or similar since that’s what she’s expressed interest in. She’s never really had hobbies before but seems genuinely interested in modifying clothes and up-cycling (I think that’s the term) thrift finds.

Can someone help me with ideas on what I could get her? She is relatively new to things and she lives in Texas (US).

I’m ok spending up to $150. Could go higher as I’ll just split costs with her dad or grandparents if the gift is excellent.
