i bought this really pretty bag, its like a small messenger bag and the strap is too short. i wanted to know if anyone had any ideas if i took a strap from another similar bag and put it on this one, how i would go about doing so?

also i don't have a sewing machine. and my sewing skills aren't "wonderful" but i really want to be able to use this bag.

help!
