Shout Out to the Experts: Inserting a Bagged Lining

Sewing Divas: Can you advise - as I can't seem to find anything anywhere (in my 5 minutes of looking): Is inserting a bagged lining as simple as stitching the right side edges of the lining and the skirt at the hem cut line of each, then flipping up the lining and attaching it all at the waist?

The skirt I will make (V8640) does not have lining instructions. Last time, I made a "regular" lining by cutting the fabric pieces again in lining fabric (minus the waistband) and assembling that, wrong sides together, at the waist. I serged the lining hem at the bottom.

This time, I thought I'd branch out, but I don't want to court disaster i.e. no original pattern modified x2 = potential eeek.

To complicate matters, this skirt has a vent at the centre back. I did find Kay's awesome post on working around the vent, but I'm still nervous about the general process.

Any feedback would be so welcome and appreciated. Kxo
