I'm not a demonstrator but I have 188 plastic cases filled with wood mounted stamps. I have mostly CTMH and SU sets. I have all of these stamps plus one shelf full of 8 1/2 x 11 card stock all stored on one book shelf I bought at Target.
The bookshelf is 6 feet tall and it came with 5 shelves (including the bottom one) . The shelves are 27 x 11 3/4" x 5/8". I added 3 shelves I cut myself from a 1 x 12 and covered those two shelves with a wood grain contact paper to match. I had to drill my own holes for shelf placement so that O could store my plastic stamp cases stacked 6 and 7 cases high. 2 of my shelves hold a stacks of boxes stacked 6 high in 4 rows and then the other 5 shelves hold a stack of boxes stacked 7 high in 4 rows. I purchased the small pegs at the hardware store that you just push into the holes you drilled to hold the added shelves. So now it is an 8 shelf bookcase.
The top shelf has my card stock sorted by color standing on it's side for easy removal. I have been unable to recycle the SU plastic wrap that comes with their cardstock so I bought gallon size plastic bags and folded and taped them to the size needed to store each color in.
I bought a whole case of 90 boxes from
www.placon.com that fit perfectly on my 12 inch deep bookshelves. The boxes that I chose are called "this box"item # TX 5931 ZZ (NO LOGO). They are identical to the ones Stampin Up uses except they have no logo (of course) and come in several sizes. They only sell their items by the case and it came out to about $60 with shipping. That's only 67 cents a box though and each box holds lots of stamps. The box I bought is about 10 3/4 x 5 x 1 1/8. and the dept is the perfect size for my shelves. No wasted space with these stacked 4 rows to a shelf.
For labeling the boxes, I buy colored dot stickers. These are sold in office supply stores and in the office supply dept of stores. I stick a colored dot on 5 inch side of the boxes in the left hand corner of each of my boxes that are sorted by category.
I use
Red dots for Christmas stamps,
blue =backgrounds and borders,
yellow=summer,
green =flowers and garden,
orange= messages and alphabets, I also draw happy and sad faces for sympathy/get well on the orange circles
pink=baby and children.
For other categories I use my punches to punch out shapes that can easily recognize at a glance.
A yellow dot sticker with a orange balloon punch out on top=birthday,
A yellow dot sticker with a orange leaf punch out on top=Fall,
A yellow dot sticker with a blue fleur punch out on top=vintage stamps,
A yellow dot sticker with a pink oval punch out on top=Easter,
A red dot sticker with a white heart punch out on top=love (Valentine,anniversary,wedding),
A red dot sticker with a white school house or apple punch out on top=school/graduation/sports,
A yellow dot sticker with a orange bear punch out on top=animals,
A blue dot sticker with a yellow cake punch out on top=food,
A cut sticker that has been pieced together in red white and blue= 4th of July/patriotic,
A yellow dot sticker with a red music note punch out on top=music.
I then use the regular white labels and write the names of the stamps that are stored inside. I underline the title in red if it's SU and underline in blue if it's CTMH and stick the label on next to the dot stickers.
Hope this is helpful, Nan
