I confess I'm in awe of anyone who can design and make bags. Quilts are 2D and bags are 3D and that whole 3D design and construction thing baffles me.
And also, and I know this is a weird thing to say, but these bags look to me like they were bought in a shop (albeit a very fabulous shop) and that's important to me - I don't want someone to come up to me and say - ooh I like your bag / dress / jumper - did you make it yourself? because I don't want to walk around looking home made.
As well as extensive detailed instructions for each bag, here are supplementary chapters on choosing and using interfacings and hardware as well as advice on choosing fabrics plus a whole page of pictures of the bags made up in different fabrics so you can see the difference.
There are lots and lots of useful drawings and diagrams throughout as well as top tips and advice and suggestions.
And finally the bags are all graded in terms of difficulty which is really important if (like me) you're a novice bag maker because you don't want to get discouraged by trying too hard a pattern first.
