To sew with a twin needle, your sewing machine must have:
* zigzag capability
* throat plate that has a hole wide enough for the double needle
* 2 thread spool holders
* zigzag foot or another foot with an opening wide enough for the twin needle
Don't worry if your machine manual doesn't mention twin needle stitching. Mine didn't but my basic machine (Singer Esteem) handled it just fine.
