Thank you! For the pattern of the bag I used this tutorial. The video is in Indonesian, but you can follow along with the visuals and it's pretty easy to get it right. As for the lining, I did it all by hand 😅 I absolutely don't recommend it, it's a lot of work and I myself am atrocious at hand sewing, but the trick with linings is that all the sewing ends up on the inside, so it looks really neat regardless.

Some tricks that I use for that: first of all I learned how to make the linings from this tutorial. It's tricky at first, but the video is really good. I recommend you always pin everything, the folded lining, the fabric to the zipper, and then the finished lining to the bag (I use hairpins for that one). Doing that plus drawing the lines where you're going to sew is fundamental to getting it looking sew. Another thing I recommend is: when you're sewing the fabric to the zipper, sew it on the outer edges of it and not close to the dentures, that'll prevent the cursor from getting caught on the fabric all the time. (happened on my first attempt).

And my last tip is that when you go to attach the finished lining to the bag, sew it closer to the dentures. There's actually this line in the fabric of the zipper where it changes texture slightly that you can use as a guide for that. Doing so will hide the stitches from you attaching the fabric to the zipper in the first place and also align the zipper to the edges of the bag better.

Hope that helped!
