I have an almost 10' X 2' shelf in front of the windows across the end of my kitchen (bump out.) The ends rest on two IKEA cabinets with three shelves each. The middle, between the cabinets has a divided shelf beneath it which also stabilizes it. Each side is wide enough to hold two 'silver trays' full of pens, and tape runner, etc. The middle section is just the right size for a ruler and my 12 inch papercutter). I have a little pail on top containing my most used tools - pencil, black, silver, gold pens, corner round scissors, needle, tweezers, cutterbee scissors.
On the left side, bottom shelf: a bin exactly the size of the shelf where I put all my stickers - didn't like 'organization' in that area, too many odd sizes, categories, etc. i'd rather rummage. On the second shelf "smaller" three drawer sterlight drawers with small punches, hand punches, adhesives, pop dots, etc. On the top shelf "larger" three drawer sterlite drawers with large punches (one whole set), stamp sets (only have two or three), my tool kit and boxes of jewelers round tins with my -er 'schmuck' like beads, eyelets, etc.
Right side, bottom shelf - albums & pizza boxes full of page kits for projects in progress.
Second shelf - bin same as sticker bin on other side but this one holding envelopes of photographs and ziploc bags full of memorabelia for future projects. I should probably have this somewhere else. Top shelf has bigger rotary cutter.
On the right hand end of the table top stands a 4 shelf bookshelf containing, idea books, coloring books, xyrons, templates in a binder. But where, you ask, is the paper? Well, there's approximately 6 feet between the end units. So I have all my paper in hanging file folders in a rolling file cart. When I'm not sitting there, it is tidily underneath, next to the office chair. When I'm working, It rolls out in front of the right side end unit.
You really have to assess your style of scrapping. I don't use a lot of 'stuff' beyond a few eyelets or a bit of fiber now and t hen, so I don't need much storage for that sort of thing. You could well need WAY more storage than I have, depending on the size of your stash.
I have an ott floor light, ceiling light, and two windows. It is NOT enough because i can't get the Ott light over my work, the arm isn't long enough.
Happy Planning!
