Love this site! I use:
a piece of plastic guttering with holes drilled in it to hang at the bottom of my pegboard (see my Avatar) to store my leader grips and aluminum yard sticks.
a kitchen island from ikea for a cutting table
wood closet shoe organizers for storage
old kleenex boxes with fabric liners to hold patterns on shelves
music stand for holding books while I'm working
cheap placemat to sew all the decorative stitches on my sewing machine - I write in the number for the design and can find one at a glance
ice cube trays for storing bobbins - got the long kind for water bottles
springs from my kids baby crib to hang on the wall - use S hooks to hang stuff on it
formular insulation board for design wall
