It has medium-light interfacing and light fusible wadding to give structure to the outside of the bag and medium-light interfacing on the lining to help it hold its shape (to the outside of the bag). It closes with a magnetic snap and has a zip pocket and a compartment pocket in the lining.
I also made a Hobo in a super-bright print!! I kept it really simple - straight off the pattern with no variations.
The lining includes a zip pocket and a compartment pocket that has this pleated section for a mobile phone (I hope that you can see it ....it photographs badly in this busy print!)
And the bag closes with a zipper gusset and a button loop.
