Making your own Fridge Magnets is great fun and really is a low-cost activity. We have 3 different types of magnets that lend themselves perfectly for this application: Ferrite Disc Magnets – Low cost with a reasonable holding force. Simply glue in place. Flexible Magnetic Rubber – Low Cost and extremely versatile. Flexible rubber is available in sheets for you to cut to size, pre-determined kiss cut shapes to save you time and these can be either glued in place or can be purchased with self-adhesive backing. Neodymium Disc Magnets – This is the magnet if your design requires a small but powerful magnet. They are available in a vast array of sizes and strengths and can be simply glued in place.  They are also available with self-adhesive backing.
