Help with choosing something cool for my sister Sewing Machines Parts and Sales in Los Angeles

Hi Sewing, can you guys help me choose something as a gift for my sister? She loves sewing, she’s good with a machine, she done loads of cross-stitches, she makes heavy material throws for the sofa and all types of clothes. So I’m a little out of my depth at picking something she would find useful or that she hasn’t got already. Any ideas, anything new or ‘must have’ in the world of sewing? Many thanks.
