Below are some pictures of my additional units and what I've used them for.
This is a base unit and upper tier that I am using for my purse/tote/bag/wallet patterns on the bottom and my purse hardware/supplies on the upper tier.
Floor Model with an extra tier. These are larger sewing notions/patterns that are too big or bulky for the regular base unit.
Mini with miscellaneous sewing notions. This one is located in between my cutting table and ironing workstation.
Base unit with upper tier and extension. This one I am using for sewing patterns.
I have this on the wall over my ironing station.
Most everything pictured on these was in drawers or stuffed in plastic containers. They are now out and handy and I can find what I am looking for in an instant. I'm in heaven! It is amazing how much more creative you feel when you've got an organized space to work in. Now if I could just translate that to the rest of my life!
