This instructable shows you how to build a magnet board using a 24 x 36 in. plastic poster frame. These frames are inexpensive, fit common poster sizes, and single tin sheet usually can be purchased in this size. You can scale the design up or down for other sizes of frames as desired.
Buy super-strong, adhesive-backed, disc magnets for your poster magnet board projects.

About The Tin Sheet: Magnets will not stick to aluminum, copper, brass, etc. The sheet can be smaller than the frame. 30 gauge sheet can usually be found at building supply stores in sections that carry heat , ventilation, and air conditioning ducting. Otherwise, suppliers of sheet metal in your industrial districts will usually cut you a piece to size. Bring your gloves to handle it.
