The above age and time guidelines are estimates. This project can be modified to suit other ages and may take more or less time depending on your circumstances.
Place your motif fabric, face down on your work surface. Set the batting piece on top of the motif fabric. Glue a magnet to the center of the batting. If your completed magnet will be more than about 2-inches square, you might want to consider using a couple of magnets, spaced evenly. Make sure the magnet will not be too close to the edge of the finished magnet edge because then it will not fit under the sewing machine foot. Let the glue dry.
Next, lay the second piece of fabric, which will be the back of your magnet, on top of the batting. The right side of the back fabric should be facing out. Pick up all of the pieces, making sure they all stay together. Flip the stack of fabric and batting over and sew around the motif as desired.
Use a pair of pinking shears to cut off the extra fabric. Cut close to the sewn line, but make sure you do not cut through it. Your fabric magnets are now ready to stick up on your fridge or anywhere else you want to use them.
