Messenger bags are a staple of the modern mobile technophile and for that reason you can end up paying over $US100 for something you can make yourself for $US10. Amber Price, over at Make Projects, shows you how it takes little more than three yards of fabric.
As you can see from the picture above, Amber chose a flower pattern for her messenger bag. You can choose whatever you like, or get custom-printed fabric for a more unique option. You just need three yards. You'll also want to use a sewing machine to make sure the bag is nice and sturdy. Although I haven't made this specific bag, I have made a few in the past and it's actually very easy. The hardest part involves figuring out on which side you need to lay each piece of fabric so you don't accidentally end up with a bag that looks like it's inside out. Amber does a good job explaining these steps so if you follow the guide over at Make closely, you'll have a cool custom messenger in no time.
