I'll mirror what Gorgon said - sewing is a core component of working with any fabric. You simply can't glue two pieces together and expect it to hold up to any form of reasonable strain.
Get some scraps together and practise. You'll really appreciate the time you put into learning the skill, since it can be applied to other situations (for example, I've learned to alter clothes and apply patches to clothing since learning how to sew), and you'll come away with higher-grade pieces at the end. You can either sew by hand, or find a cheap machine to sew parts together - my machine only cost $30 and has been a life saver.
Either way: the easy route is rarely the best route when it comes to costuming. Apply yourself and put some effort into learning some new skills. You'll be glad you did.
