Nintendo DS Lites are quite small, but the hard case they supply is quite bulky. A soft cozy case like this is often much more practical.
You could also use the pouch to keep a collection of other vital personal items such as your classic cell phone, iPod touch, iPhone, Blackberry, small camera, mp3 player, money, business cards, make-up, notebook, pens and pencils.
I crocheted this one in a variety of blue and grey yarns. It closes with a loop and handmade button.
The cozy measures 4 x 6.5 inches and will stretch a little if required.
