Khamryn, a cosplayer friend of mine, suggested another corset supplies site!
Farthingales Corset Making Supplies – This site boasts patterns and all the supplies you could need in making corsets. The pricing is all in Canadian dollars, so you have to do a little conversion here and there, but via that, the pricing is decent. Shipping and handling is also decent, since everything is coming down from Canada. Definitely worth checking out!
Hope this resource can help some of you out! You can see this post at CosIQ as well!
