Wow!! I downloaded the manual to my $10 Babylock serger I got yard saling, and you can chain-stitch with it. That is awesome for some of the projects I take on, like fitting bride's and bridemaid's gowns, then permanently sewing on top, or easier ripping out. Most of the girls are so excited, and want to be measured today for a wedding in 6 months, and they change in the meantime, and are tough to fit sometimes. This will make it easier to alter for sure, and is very fast, so can just straight-up use it for linings and such.
