This bag came to be as I needed a bag to use as carry on when flying to Stockholm, and as it's for use in Stockholm, it had to be big enough to fit both my laptop, an extra sweater and everything else I need while travelling or for a full day on the town. This bag is perfect for both! This stylish, no fuss design with a simple big exterior pocket and a zippered pocket at the back is perfect for the advanced beginner all the way up to the advanced bagmaker who potentially could spice it up in numerous ways! It has a zippered pocket in the lining and some open lining pockets for cellphones and other little things. I hope you'll have as much fun making your bag as I did and that you'll get just as much use out of yours as I'm getting from mine! BASIC SKILLS NECESSARY The pattern has 42 color photos showing every step of making the bag but basic sewing skills is naturally good to have. SIZING / FINISHED MEASUREMENTS ~12" high and ~18" wide at the top.
