I used cotton linen blend fabrics with a geometric pattern and a complimenting cotton fabric for the lining.
You can check out a few others I have sewn here in a previous post.
To sew one of these cute little pouches you can find an easy to follow tutorial at Sotak Handmade. She provides you with dimensions for a smaller version of this pouch which measures 3"W x 3.25"H when finished. I adapted her pattern to make a slightly larger pouch. My pouch measures 6" W x 5" H when folded.
