Here are some 'before' shots... well, really 'in progress' shots, since the shelves were just installed, and I didn't have the foresight to take pix before I moved things out.
This shelf is in the far corner of the room, and has room underneath for rollaway drawer storage units.
This shelf fits nicely over my work table, so I can store supplies there I will be using more often than others.
This shelf is next to my sewing machine and adjacent to my worktable, so it will be handy for storing 'How to' books, sewing books, sewing supplies, etc. I will post more pix when I have done the magic conversion from chaos to order...
