Frame folk
I'm surprised at how few , if any of you mentioned a easel type design table. After doing that dangerous dance of the client saying "let me hold it up for you - you're the expert" one two many times I came up with a way we can both get back from the design and assess it. I've been using this set up for about 5 years now and having just moved (again!), this latest incarnation is the best by far. At 7 feet by 4 feet this 5/8 plywood is about 3 1/2 feet off the ground and about a foot and 1/2 away from the wall at the bottom affixed to the wall at the top. It is covered with velcro sensitive, neutrally colored fabric that can be swapped out every 6 to 8 months or so, or as needed. I put a length of moulding along the bottom to support whatever needs it (mat board not being used) but I use strips of hook velcro, little foam core squares with velcro and the frames themselves to hold mats and the art together. I am fortunate to have about 8 feet of room in front of the design area so the client (and I ) can back up and get a good approximation of how the piece will look on the wall.
I built a mat rack underneath the easel that runs the length of the area - 9 feet (using 3 lengths of metal moulding shaped in the ubiquitous triangle and supported at a couple of points) and this makes reaching for mats soooooo much easier. I only show acid free but quite a few brands so one half is for colors and the other half has the rag samples, specialty mats (those costly ones that if you misprice you cry, cry cry), all the whites (divided into 3 sections - white, off white and cream) Intaglio, hand wrapped and regular fabric mats and everything else. Since I'm struggling with the 2 3/4 vs 4 inch thing, I made the dividers 5 inches wide out of the appropriate color and labeled them with big white computer generated tags so they are very visible.
