Overview
Not a basic mechanical heavy duty model, the SINGER Heavy Duty Sterling is computerized, with an LCD that shows stitch, length and width. A metal interior frame and strong piercing power push through denim, canvas and multilayer seams.
A metal frame with touch stitch selection gives home sewists heavy fabric power plus a wide stitch library in one machine. The throat space is compact for bulky quilt work, and the feet list differs between bullets and specs.
Who it's for
Home sewists who switch between heavy fabrics and decorative or stretch stitches. Quilters who push full size quilts through the arm need a larger harp space.
Pros and cons
- Metal frame for stability
- Wide stitch library
- Shows length and width on screen
- Clear top drop-in bobbin
- Compact throat space for quilting
- Feet list varies across listing fields
- No automatic thread cutter listed
Performance notes
Heavy fabrics feed well because the needle pierces with extra force and the frame resists flex at speed. Presser foot pressure has to be lowered for sheers, or the feed dogs can pucker light fabric.
