I haven't posted this yet so thought I would share
this is one of the teachers gifts I made, Unfortunately I didn't take a photo of the lining which I actually liked more than the bag.
I used a tutorial which I found on pinterest, which was all in chinese?! so had to do a bit of guess work

It was fun and fairly quick to make, If i were to do it again I would make the strap around the middle a little longer and possibly the case a little wider too. but i liked how it turned out any way.
