Overview
A spare bedroom table or a dorm desk is enough room for this Brother sewing machine, which is light enough to put away after each project. It sews basic, blind hem, decorative and quilting stitches, and a free arm takes cuffs and sleeves.
Easy threading, a jam-resistant top bobbin and a long warranty make learning less frustrating. The stitch list is short next to computerized machines, and the listing gives no speed or throat space.
Who it's for
New sewists and occasional menders who want a light machine that is simple to thread. Experienced sewists after lettering, wide decorative stitches or quilting space will outgrow it.
Pros and cons
- Light and easy to store
- Needle threader built in
- Jam-resistant top drop-in bobbin
- Free arm for sleeves
- Small stitch library
- No speed or throat space listed
- No screen for stitch settings
Performance notes
Stitch quality on light and medium fabrics depends on the needle and tension matching the fabric, since there is no automatic tension listed. The free arm lets tubes like sleeves rotate around the needle without bunching.
