If you stick to the pattern, it will not take 16 hours, but I added details. For the first one, I added a simple pocket to the front:
However, I didn't think through the pocket and ended up placing the button too far down:
For the the next one, I got the idea to make a pan-African flag design...I already had black fabric and just enough red and green scraps to accomplish this. For this one, I put the pocket in the inside:
To make an applique in the shape of Africa, I did a quick google image search and traced the shape on tissue paper. After I applied the applique, I outlined the shape with beads. I think it came out pretty well, but I think next time, I'll make the applique bigger:
Overall, this pattern was very easy. There is one step (step 8 - something about attaching hook and loop tape which I don't have and don't even know what it is) that I still don't understand so I omitted it and it doesn't seem to be all that important. As such, I do recommend this pattern. As you can see, you can easily add your own personal touches.
p.s. The bags are available on Etsy
