Below is a link to "The Artist's Network" and a great article on Framing that you may find helpful. My best advice is to use a reputable framer that understands the medium you are having framed.
"Like the setting for a diamond, the frame around a work of art is the finishing touch, the element that completes and elevates a painting, presenting it to the viewer in its best possible light. Framing, however, is an art in and of itself"
