Their interfacing selection is quite large, and I got some of the woven fusible, which seems to be a great slightly cheaper alternative to what I normally use; it's more per yard, but it's 46" wide compared to 20". I also requested a sample of the medium weight non-woven fusible interfacing, which they carry in white and black. I've had a chance to try out the woven interfacing, and I find it's comparable to the name brand stuff I usually use. It fused easily and didn't wrinkle on the finished product.
You do need an account to access prices and order, but it was really quick for me; I just filled out the form, and received an email the following morning with my account info. So don't let needing an account deter you. I also needed to call and ask some questions, and I was able to get help by phone, hassle free.
I found the shipping rates really reasonable too! Free shipping on orders over $200, and low shipping rates on orders below $200, for quick reliable shipping.
