Singer Heavy Duty 4423 in Meltwater Blue: Metal Frame Power for Thick Fabrics
The Singer Heavy Duty 4423 in Meltwater Blue is built for heavy duty projects, from denim to canvas. It has 97 stitch applications made from 23 built-in stitches, a one-step buttonhole, a built-in needle threader, and a top speed of 1,100 stitches per minute.
Use it to create original costumes, sew personalized fashions, or make decorator pillows and curtains. Singer's Online Owner's Class covers threading, stitch selection, and making a buttonhole, and the free SINGER Sewing Assistant App covers machine parts and set-up.

Heavy Duty Frame for Thick Fabrics
The heavy duty metal frame and powerful motor handle denim and canvas, and the stainless steel bed plate lets fabric glide as you sew. Adjustable presser foot pressure suits lightweight sheers, and the extra-high presser foot lifter makes room for thick layers.

One-Step Buttonholes
Place the button in the buttonhole foot and the machine sews a buttonhole sized for that button in one step, with consistent results every time. A button sewing foot is also included, and the drop feed lowers the feed teeth for sewing on buttons or free-motion work.

97 Stitch Applications
Turn the stitch selector dial to choose from 97 stitch applications made from 23 built-in stitches. A stitch application is a specific technique you can sew with a selected stitch.

Built-In Needle Threader and Drop-In Bobbin
The built-in needle threader threads the eye of the needle without eye strain. Under its transparent cover, the top drop-in bobbin shows your thread supply so it does not run out mid-seam.

Adjustable Stitch Length Dial
Turn the length dial to set the distance between stitches for techniques such as appliqué and basting. The adjustable stitch width is 6 mm, and 3 needle positions suit topstitching, edgestitching, and zipper application. A reverse lever secures seams at the beginning and end.

6.25 Inches of Sewing Space
There are 6.25 inches of space to the right of the needle, which gives larger projects such as quilts room to move. Slide off the removable storage compartment to reach the free arm for trouser hems and sleeve cuffs.

Included Feet and Accessories
The general purpose, zipper, buttonhole, and button sewing feet come in the box, along with an edge/quilting guide, needles, bobbins, spool caps, an auxiliary spool pin, a spool pin felt, a screwdriver, a seam ripper/lint brush, and a soft dust cover.
