Sewing in a Straight Line is a great book with tons of easy projects.  I made a jewelry case and a cosmetic bag.  The fabric is some type of drapery fabric I picked up at the free table from my guild.  It is stiff so great to work with on these types of projects and I didn't use interfacing.

This jewelry holder has zipper compartments and a ring holder.

The cosmetic holder could be made with denim for an even sturdier pouch.

I had these cute Tim Holtz labels for a fun flair. These bags will be accompanying my on my next trip.
