If you have a bunch of boring three-ring binders, you can cover them with various pieces of fabric to decorate them and tell them apart. There are different ways you can cover a binder with fabric. One of the ways is to sew the edges of the fabric. If you have a the right kinds of adhesive and a few simple supplies, the process is much easier. You will also be able to make them softer to hold in your hand.
Place a sheet of thin foam in front of you. Close your three ring binder and hold it so that the outside of the spine is sitting flat on the foam. Trace around the edge of the spine on the foam with a pen. Do the same with the front and back sides of the binder and cut out the pieces you traced.
Spray the outside of the spine with spray adhesive and press and smooth the piece of foam down onto it. Wait at least 4 hours for the glue to dry before handling it again, and do the same for the foam for the front and back covers of the binder.
Lay a yard of fabric in front of you and smooth it out. If the fabric has a pattern on it, make sure the side with the pattern is facing down. Place the opened binder on top of the fabric with the rings facing up.
Measure a distance of 2 inches around the outside edges of the binder and trace a line at this distance all the way around, except the top and bottom edges of the spine. Where the spine is, there should be a squared opening because you won't be able to fold the edge of the fabric over to the inside of the spine. Cut the fabric at the line you traced.
Place the piece of fabric you just cut out face down again. Spray adhesive on the foam on the spine of the binder. Press it down on the fabric and make sure the edges line up. Smooth it down and use the edge of your fingernail to press and smooth the fabric along the edges of the foam. Also smooth the fabric where the edges of the spine bend at the edges of the front and back covers. Wait 2 hours for the glue to dry.
Spray adhesive on the foam on the front and back covers of the binder and smooth the fabric across them. Wait 2 hours for the glue to dry before touching it again.
Fold the edges of the fabric over the front and back covers and glue them down with hot glue. Hold the edges of the fabric down every 2 or 3 inches with bulldog clips while the glue cools, especially on the corners where the fabric overlaps. Wait 30 minutes and remove the bulldog clips to use your fabric-covered three ring binder.
