I made this little bag up the other day.
I used the free pattern and tutorial I found here.
I like the way this bag turned out but next time I will make a few changes.
I don't like such a stiff bag so I will use a lighter weight interfacing and
I will move the straps a little closer to the middle.
It was supposed to close with a magnetic stud but I decided not to use one.
I figured the bag was deep enough that nothing was going to fall out.
I like having the pocket on the inside so I can easily find my phone.
I wanted to sew a little fob for my keys in the lining but I forgot. Grrrr...
I made my own navy piping which I am pleased with.
It is actually really easy and I'm going to use it much more often.
