Lastin?

[KaterJean]

 I just ordered some lastin and it said it needs to be zig zagged down. Can I encase lastin?

[caraneden]

Yes. They just mean you want to zig down the center of it while stretching it. Encasing it wouldn't touch it at all.

 Yes, it can be encased during topstitching after you stitch it down, but you can't tack and encase it

I am personally not a fan of it, but I loved it for dolly dipes

Normally when someone says 'encase' it means tacking the ends only and than encasing when you topstitch. You cant do that with lastin. However, you can zig zag the elastic down the length and than encase around that if you want. I prefer to just top stitch the non-elastic parts and skip over the casings when I zig zag elastic though. Just personal preference!

 I'm making swim diapers and think lastin would work better for that purpose. Thank you! I don't like to ziq zag elastic down and didn't know if I really needed to with lastin.
