I second Wazoodle. I've ordered lots of different materials from them - organic cotton, organic bamboo, zorb, cotton sherpa - and have always been really impressed with the quality. Amazing prices (the organic cotton jersey is more than twice as much at my Fabricland), fast shipping and fairly decent communication.
I have heard however that some mammas have not had such good luck with their shipping and communication.
Happy mumma to my boys Henny Tom (Nov 30, 2008), Arlo Odie (Oct 5, 2010), and baby SISTER! due mid-Dec 2014.
