Shelves are an easily obtainable addition to your creative space. They can be found (sometimes even for free) on Craig's List or Freecycle, but are absolutely worth purchasing.
I purchased mine at Staples they aren't the greatest quality, but they are inexpensive. These tall ones run about $50, but go on sale for 50
% off every other month or so. They
also deliver for free!
Building this shelf cost me less than $40. It took a sheet of plywood, a couple of 2x4s, a few brackets and a handful of screws. For the 2 hours it took to put up, I have 35 square feet of "found" storage space. That is about $1 per square foot!
This is the second "found" space shelf that I have. It is above my sewing table. This is the hardest to get to shelf in my sewing room so it houses things I rarely use as well as holiday ornaments and other household items that have made their way into my sewing room.
