That is the question!!!

I am just curious. When framing an oil painting, do you cut a hole in the paper backing, or do you leave the dust cover in tact with no "air hole to allow it to breath"?
Mat Framer this has been discussed and debunked both here and on HH. Those little holes are not so good for breathing as they are for breeding INSECTS ( roaches ,siver fish etc. also it is a great pace for dust and mould to accumulate.

I think the joking adage is "if it doesn't have LUNGS it doesn't need to breath"

do a search on the topic and insert Hugh Phibbs' Members' number.Also if you can go far enough back try checking out Orton's opinion .I was glad to see a recent reply he made maybe he'll refresh his reply for you.
I just had a canvas come in the shop backless! I thought it was better to have full dust cover!
Thanks, everyone!!!

I like the answers!!! You all agree with what I have been doing for the last several years. The only exception is to put a backing board inside to protect the back. I like that even better.
All of these are good answers.

If you want to know ALL about framing stretched canvas art, contact the Canadian Conservation Institute and get the "CCA Notes" on the subject. Also, the AIC brochure entitled "Caring for Your Paintings" is very good & concise.

One more reference: The PPFA specifications written by Merrill Grayson for the stretched-canvas section of the MCPF exam are excellent.
