Not my personal list, but some things I was considering sending to my "little girl"....I'd love to see her comments!
Seam rippers are ALWAYS good.
Needles, both hand and machine.
Decorative threads.
Specialty rulers.
Sewing machine attachments...but would depend on what kind of machine folks have.
Non quilty?
Book, mug, coffee mix or tea bags, candy, sugar free candy, bath salts, fancy soaps, lotions...an extra for DH and/or kids along with a little something for a pet.
Hand made?
Mug rug, table runner, placemats, anything embroidered...
