The outside fabric is a very fine, beautiful tweed which I bought in the Scottish borders. The fabric has woven-in wide stripes of different colours. I have used two different colours on the front and the back of the bag.
The top with the zipper is one colour only.
The colours for the bottom panel change at the centre of the panel at the bottom.
The lining is also a woollen fabric with woven-in squares and has one large slip pocket for a laptop, two smaller slip pockets for smartphone, etc. and one narrow pocket in the centre of these two for one or two pens or pencils.
