Christmas gifts for someone who likes to sew for a hobby? Sewing Machines Parts and Sales in Los Angeles

My stepmother loves to sew and I’m thinking about getting her something for her hobby for Christmas. I feel like she might already have everything she needs for sewing, so what else can I get for her that would be fun and not so basic? Line a really fun fabric? A bunch of patterns? Buttons or batting? I’m at a loss but she does like to make quilts and dresses for the grandkids. Thanks for the help!
