Back Lining Construction
Just as you did with the front, there is a lining which needs to be constructed separately from the outside fabric.
If not already done, using the master pattern, cut 1 from lining fabric.
Patch pocket (for the top half of lining):
Just as with the front lining patch pocket, cut a 3 x 5 piece of lining fabric and create a patch pocket by folding under edges and topstitching it to the lining. This pocket has a similar purpose to the one on the front lining. It is handy for a key card, a pack of gum or other small items, and it assures that all contents don’t drop to the bottom of the bag.
Lower Pocket:
- Draft a pocket of your choice. As you can see, my preference is to make a spacious pocket with elastic at the top and mitered corners at the bottom. This is perfect for my Kindle. It goes almost from edge to edge. I could have placed this lower but didn’t realize this until the bag was assembled. There’s always next time!
- Also you can see that and a narrow slit pocket or two for a pen.
Back Assembly:
As you did with the front, place wrong sides of the back outside and back lining together. Baste close to the edges and match with the master pattern and trim any errant edges. You are now ready to insert the zipper and create the gusset, which will be covered in the next lesson.
FabriCate & Mira 
I was so happy to see posts on your blog again especially about the travel bag. I love your ideas and writing. Thank you so much for making a tutorial of your process. I’m slowly getting together supplies since I’ve never made a bag before and probably going to cut up an old rain jacket for the exterior, but I’m going to do this!
So glad you’re going to give it a try. An old rain jacket is perfect for this bag. Good luck and let me know if you have any questions along the way as this isn’t a tested and polished tutorial.
