One inexpensive place I have stored craft supplies for many years is in my girls' old lunchboxes. Here is one. We have a stack of these in a closet under our stairs. They are very portable. We have several Barbie versions and a metal Mickey Mouse one. They bring back happy memories and are very functional.
When we were rearranging our house a few years ago, I ended up with this shelving unit for sewing supplies that my husband had been using before. It is about 40" tall and 36" across. We originally purchased it at a discount store like Target or at Home Depot. As cheap as I am, I am sure it was less than $70. It keeps things hidden and tidy.
I bought this next unit at an office supply store for about $30. It is perfect for scrapbooking-- if you are using 8.5" x 11" paper.
Finally, I claimed a small, under the eaves closet to store my fabrics and quilting supplies. I LOVE clear plastic containers. Big Lots is a great place to buy them. I utilized a hat rack already in the closet to hang hoops. There are also acyrlic rulers at the very top of the rack. I have my cutting mats and other rulers hanging from a peg.
Even though it is a tall stack, I can find things very easily now.
Where do you keep your "stuff"?
