Why are my Overlock stitches loose?

Should you Overlock before or after sewing?

You can use the overlocker to finish the seams together after constructing your garment but before doing any topstitching. You’ll want to try on the garment and make sure the fit is spot on before finishing the seams in this way.

Do you Backstitch on a serger?

Since you can’t backstitch on a serger, it’s important to finish each stitch to prevent the threads from unraveling. Instead of leaving them long or simply cutting them off, secure your serged seams using one of these simple, tidy finishes.

How do you adjust the Overlock stitch width?

If the overlock uses two needles, the stitch width can be adjusted by removing one of the needles. This can be done only when a three–thread stitch is used. The stitch length of an overlock machine may vary from 0 to 5 mm (0–0.2 inch). The stitch can be adjusted by turning a dial, moving a lever, or loosening a screw.

What tension should I use for thin fabric?
