There’s are alot of good choices.

Spend at least $200-300 on a good brand, like Bernina, Janome, or Singer.

AVOID big box stores. Instead, buy from a dealer near you, if possible. You can then trade up with them if she wants to eventually upgrade. I’ve only done this twice in 40 years of sewing so it’s worth it to start out with a good quality machine.

Other tips:

• Test drive before you buy.
• Get it serviced once a year.
• Take some lessons to learn good habits.

Sew on!
