By special request due to the storm approaching the east coast, I am sharing this post early.
This week we are attaching the balloony section we gauged last week to the covered paste board.
Cotton Work Bag
We are attaching the long section we gauged last week to two of the the covered pasteboards (the ones that are backed with the lining fabric.) The gauged fabric will be attached along the curved section of the pasteboard. The flat side will not have fabric attached.
We will attach the pasteboard and the gauged fabric right sides together with the decorative side of the pasteboard, using a whip stitch. Line up the center point you marked on one side of the gauged fabric with the bottom center of the pasteboard. Pin these points together. Line up the quarter points with just above the curve on the pasteboard. (I’ll get a better photo of that.)
On each end, fold a quarter inch of the gauged fabric under. Line this fold up with the top of the pasteboard curve where it meets the flat side. Pin both ends as well. (sorry, I will try to get a photo of this.)
Using a whip stitch, attach the folds of the gauging to the pasteboard. Go through both the decorative and lining fabrics, but not the paste board.
When one side is finished, it will look something like this. You may need to coax the gauged fabric to lay flat aligned with the pasteboard. (outside and inside shots.) (Yes, I make use of the salvege.) 
Repeat the pinning and whip stitching process with the second covered pasteboard.
When finished, you will have two sorta horse shoes attached to the gauged fabric. Take some time to play around with how these fit together. It is a rather nifty combination. 
Lay the workbag out flat to check your stitches. 
You have completed this week’s step. (You can turn it right side out if you want.)

Silk Work Bag
We are attaching the long section we gauged last week to two of the the covered pasteboards (the ones that are backed with the lining fabric.) The gauged fabric will be attached around the entire circle on each side.
We will attach the pasteboard and the gauged fabric right sides together with the decorative side of the pasteboard, using a whip stitch. Mark each circle in quarters. (pencil on the inside lining is fine.)
With the first pasteboard – Fold a quarter inch under on each end. Line these up with the top point on the pasteboard. Pin. Line center point of the gauged fabric up with the bottom point on the pasteboard and pin. Do the same with the side quarter points. (Sorry for the lack of photo.)
Using a whip stitch, attach the folds of the gauging to the pasteboard. Go through both the decorative and lining fabrics, but not the paste board.
When one side is finished, it will look something like this. You may need to coax the gauged fabric to lay flat aligned with the pasteboard.
Repeat the pinning and whip stitch with the other pasteboard side.
When finished, check your work. Once you turn this one right side out, it will be be difficult to turn it inside out again.
If I Had My Own Blue Box: 
Thanks for the early post!
You are welcome.
I wish I had a special “snowed in” project with directions written up already for people.
