Here's an iPad Bag I sewed for my husband.
It has a front flap pocket with pleats for the charger and a zip pocket for pens, stylus, etc. When the main compartment is closed the zipper pocket is hidden behind the flap.
The strap is detachable just in case he wants to use it in his main briefcase.
Update: I forgot to mention that I design this bag (pattern) with the features my husband requested.
I also finished and listed on my shop this drawstring backpack made with a pattern from Dog Under my Desk.
I don't have much time now but wanted to post the pictures and show you.
