The Japanese have got the right idea with double gauze, it is lovely because single gauze is too see through someone came up with the idea of attaching two layers together. It consists of two layers of lightweight gauze which are attached together using microscopic stitches. It is light and airy and easy to care for but... you knew there was a but didn't you? It can be a pain to sew with, don't let that put you off though, as seams tend to fray try a French seam (easy, and a great technique to add to your skills) or sew with a 5/8" seam allowance and finish off with a zig-zag (or overlock stitch if you machine has it). If you have a serger then finish the seams with that.
Since you will be changing your needle for a new project, what do you mean you don't? tut, tut, tut, OK I am guilty of that too, anyway, try using a 70/10 or 90/11 sized needle.
In Japan double gauze is a popular fabric for baby clothes because it is light and airy and very breathable, it is also used as wash towels and clothes for mopping ones sweaty brow but don't stop there, you can also use it to make quilts or baby blankets, it really is a versatile fabric.

Nani Iro range by Naomi Ito and Echino all have the prints available in double gauze and the latest line of Heather Ross too. Of course I stock some double gauze in my shop but it isn't as popular as the common ole cotton, I feel a bit sorry for it really.
