Where is the best place OR what is the best way to purchase archival materials for DCO mount of documents? I am in the Portland, Oregon area and have called a few art stores... nothing yet.
 
I called Talas to ask for the materials, hoping they have a kit for DCO mounting. The store employee had not heard of DCO or the materials such as fine mesh overlay. He did mention crepeline. I would like to know where framers are finding these items. Has anyone ordered these items and can you tell me what is the materials list?
Thank you.
 
If you don't have Jim Miller's book on DCO, this might be the time to get it. It was available in both printed and PDF format.

To answer your question, crepeline is one form of fine mesh overlay.

Most of the materials used could have been found at JoAnne's Fabrics. Needle punched polyester batting, unbleached muslin, etc.

As I recall Talas has a policy not to provide advice or tutorials on how to use their products..... which makes total sense.
Jim Miller's book would be a great place to start educating yourself.
 
Hi, Huckleberry. I tend to think of a fine mesh or crepeline overlay, as being for object mounting, rather than a DCO.
DCO projects often involve lightly pressing the surface of paper/fabric art against acrylic glazing, with various supports
used behind the paper/fabric, depending on various factors. Often, it's backed with a layer of thrice-rinsed muslin,
behind which are progressively larger-sizes of needle-punched cotton batting, behind which are rigid support substrates.
(Jim, or anyone else, feel free to comment if this needs a tweak).

Some of these items are available from fabric stores. As for archival materials, along with Talas, check out Gaylord Archival
(which has rolls of mylar, featured in Jim's book about object mounting) and University Products. I also highly recommend
Jim's books, as well as searching the Grumble archives. Searching 'crepeline' brings up some great chats. :)
 
It's no surprise that Talas employees are unfamiliar with DCO mounting. Other than the published instructions provided by the products' manufacturers, broad-line conservation material suppliers (such as Talas) may have little or no knowledge about how to use what they sell . As mentioned by "Finest Fabric" above, they probably would avoid giving advice due to liability concerns. Their customers are supposed to know what to do, and the suppliers usually are not educators.

A few brands of clear polyester film are available and interchangeable, such as Hostaphan 43SM and Mylar-D. The film may be available as prefabricated envelopes (which I would always take apart for use of the film), sheets, and rolls. Clear polyester film is extremely strong, so don't worry about it stretching, or tearing from a clean edge. 3-mil film is the least visible, but it's harder to handle without making accidental creases. 4-mil film is more forgiving in handling and generally good for all clear film mounting. Other thicknesses up to 7-mil may be available, but they are more visible and do not crease well. Do not use ATG tape in any type of clear film mounting.

From conservation materials supplies (Talas, Gaylord, etc.)
Mylar-D -- Clear polyester film for DCO and encapsulation mounting
Crepeline -- Fine mesh silk organdy fabric for DCO mounting
3M #415 double sided tape (to bond clear film to itself and substrates)

From distributors of framing supplies:
UV-filtering acrylic -- for acrylic DCO mounting
Museum Optium Acrylic -- for acrylic DCO mounting
Polyester fillet tape -- double sided, 1/4" wide tape with good acrylic adhesive for light-duty clear film mounting , such as ASAP Tapes #ASA600
---- (NOTE: avoid cheap fillet tapes, such as polypropylene)

From fabric and/or art supply stores:
Needle-punched polyester batting (not cotton) -- for padding in Acrylic DCO mounts
Acrylic gel medium -- to bond Crepeline and other fabrics to substrates
Tulle -- woven nylon fabric (such as for wedding veils)

Like most framing techniques, all types of DCO mounting have specific instructions and cautions. Shameless plug: buy or borrow the DCO book.
