Direct answer first: To thread a Singer Simple sewing machine, follow a straightforward sequence that applies to most models in the Singer Simple line (spool on top, thread through guides, up to the take-up lever, down to the needle, and a small thread tail). If your exact model is one of the Simple 3116/3223/3229/3337 families, use the model-specific steps below to ensure correct path and tension. Model-specific threading outlines
- General setup
- Turn the machine off and unplug for safety.
- Raise the needle to its highest position by turning the handwheel toward you.
- Place a fresh spool of thread on the spool pin and secure with the spool cap if your model uses one.
- Draw the thread from the spool and pass it through the thread guide at the top of the machine.
- Through the upper thread path (common sequence)
- Guide the thread down toward the tension mechanism and thread the tension discs as directed by your model’s path.
- Bring the thread up to the thread take-up lever and thread it from right to left (as some models require).
- Continue down to the thread guides above the needle and then toward the needle area.
- Needle threading
- Thread the needle from front to back, leaving a tail of about 6 inches (15 cm).
- Some models include an automatic needle threader; if present, engage it according to the manual.
- bobbin and lower thread (if your task includes bobbin winding)
- Wind a bobbin and insert it in the bobbin case as specified for your model.
- Ensure the bobbin thread feeds in the correct direction and through the bobbin tension if applicable.
- Final checks
- With both threads, hold the tails and lower the presser foot.
- Gently turn the handwheel toward you to ensure the needle and bobbin threads form a small stitch loop under the foot.
- Start sewing at a slow speed to check tension and feed.
Tips for success
- Consult your exact model’s user manual for the precise path, especially the order of the thread guides and any optional safety features.
- If your machine has a built-in thread guide diagram near the top cover or on the body, follow that diagram closely.
- If you encounter skipped stitches or bird’s-nest tangles, double-check that the presser foot is lowered, the needle is correctly installed, and the thread is properly seated through all guides and the take-up lever.
If you’d like, share your exact model number (for example, Simple 3116, 2263, 3223, 3229, or 3337), and I can tailor the step-by-step threading path to that model.
