Singer Prisma Heavy Duty: Metal Frame Strength for Thick Fabrics
The Singer Prisma Heavy Duty sewing machine pairs a full metal frame with 11 built-in stitches and 6.25 inches of space to the right of the needle. Strong piercing power suits heavier projects, and the rainbow checkerboard panel adds bold styling.
Full Metal Frame and Adjustable Presser Foot Pressure
The internal metal skeleton keeps the mechanisms aligned for skip-free sewing and adds stability as you sew. Adjustable presser foot pressure gives smooth feeding on fine fabrics and on thicker ones, and the drop feed lowers the feed teeth for monogramming, free-motion quilting, button sewing, and darning.

Strong Piercing Power for Heavier Jobs
Hemming jeans, sewing multiple fabric layers for costumes and home decor, and making quilts are all within reach. The machine reaches a top speed of 1,000 stitches per minute, which saves time on long seams.

11 Built-In Stitches and a 4-Step Buttonhole
Choose from 11 essential stitches for sewing seams, finishing seam edges, and inserting zippers. The 4-step buttonhole is sewn in four simple steps, and each step is shown on the stitch selector dial.

Adjustable Stitch Length and Width
Adjust stitch length to a maximum of 4 mm and stitch width to a maximum of 6 mm. Setting both to suit the fabric, thread, and technique gives you control over each stitch.

6.25 Inches of Sewing Space
There are 6.25 inches of space to the right of the needle, with a sewing height of 4.25 inches, which accommodates larger projects. Slide off the removable accessory storage tray to reach the free arm for trouser hems and sleeve cuffs.

Top Drop-In Bobbin
The jam-resistant top drop-in bobbin is easy to wind and easy to insert. A transparent bobbin and cover plate let you check the thread supply at a glance.

Presser Feet and Accessories Included
The box includes the general purpose, zipper, buttonhole, and button sewing feet, an edge/quilting guide, needles, Class 15 transparent bobbins, spool caps, and a soft dust cover.
