How to Make a Simple Key Case

How to Make a Simple Key Case

This is an old fashioned practical but simple key case.  It is the perfect way to secure your keys so that they do not tear up the inside of your purse.  Secure them simply and easily in this little case and toss the whole thing in your purse.  No problem.  I actually got this project from Sewing Times on YouTube and thought to share it with you here.  This is a fun little beginner sewing project that requires some specialty hardware that you can get here.  As an Amazon Associate I earn from qualifying purchases.  This functional little sewing project is perfect for the beginner sewist to sew something fun and practical to use every day.  

I used standard cotton fabric for the outside and lining of my simple key case and some pre-made bias binding to pull it all together.  I wanted to make this project as simple as possible so I did not make my own binding this time.  Because this project takes very little fabric I delved into my stash and pulled out some coordinating fabrics that I had previously purchased at JOANN Fabric & Craft Stores but you could head to Hobby Lobby, Fabric.com or Onlinefabricstore.net if you don’t have anything in your stash to fit the bill.  This post contains affiliate links that If you click on them and make a purchase I may receive a small commission at no extra cost to you.  

What you will Need: How to Make a Simple Key Case

What you will Need Simple Key Case

Step 1: Cut your Simple Key Case Fabrics

  • Cut 1 outer, 1 lining and 2 interfacing that measure 7 7/8″ x 4 3/8″
  • 1 outer that measures 4 3/8″ x 4 3/8″
  • Cut 1 interfacing that measures 4 3/8″ x 3 5/8″
  • 1 outer and 1 interfacing that measure 3 1/4″ x 4 3/8″
  • 1 outer that measures 1 1/2″ x 2 3/8″
Cut your fabrics

Step 2: Fuse the Interfacing

First, using the pattern piece cut the 7 7/8″ x 3/8″ interfacing.  Fuse it to the corresponding outer and lining piece following the manufacturers instructions and using a hot iron.  Trim the corners to match the interfacing.  

Step 3: Stitch the Main Pieces Together

Place the two main pieces with the interfacing wrong sides together and stitch around the outer edge using 1/8″ seam allowance.  

Place main pieces wrong sides together

Step 4: Add Half of the Kam Snap

On one short end of the main fabric piece find the center.  Measure 1″ toward the middle and make a mark.  Place the Kam snap half on that mark so that the snap side is facing on the outer fabric.  If you are unfamiliar with how to install Kam Snaps check out this video.

Step 5: Add the Inner Flap to the Key Case

Take the outer and lining piece that measure 3 1/4″ x 4 3/8″.  Fuse the interfacing following the manufacturer’s instructions.  Fold the piece in half lengthwise wrong sides together and press.  Stitch along the fold.  Place the piece over the wrong side of the Kamsnap matching the raw edges and clip.  Trim the corners to match the curve.  Stitch around the curve to secure.

Add the flap

Step 6: Create the Center

Take the outer piece that measures 4 3/8″ x 4 3/8″ and the interfacing piece that measures 4 3/8″ x 3 5/8″.  Fuse the interfacing so that there is 3/8″ on the top and bottom of the outer piece that does not have inter facing.  Fold the piece in half right sides together and stitch along the raw edges using a 3/8″ seam allowance. Turn right sides out and press.  Topstitch along both long sides.

Step 6: Add the Center

Measure 1 1/4″ from the inner flap and place the center piece.  Stitch along the top and bottom to secure.  

Add the Center

Step 7: Create the Swivel Clip Tab

Take the Final piece of fabric and fold the long edges to the center and press.  Fold in half again to conceal the raw edges and press again.  Topstitch along both long edges.  Wrap the tab around the shank of the swivel clip folding the tab in half.  Place the tab and swivel clip On the outer side of the main piece next to the center closest to the inner flap.  Stitch in place.  

Create the tab
Add the swivel clip

Step 8: Add the Bias Binding

Start by folding the binding end on the diagonal and pin with raw edges aligned.  Pin the binding all the way around the piece pinning as you go. Stitch along the first fold of the binding to secure.  Fold the binding over the raw edges and clip.  I use wonder clips for this you can get them in my Amazon shop here.  Stitch the binding to the piece.  You can either do this by machine or by hand.  I prefer to do it by hand using blind stitch for a more invisible look.

Step 9: Add the Lobster Clasps

Place the rounded part of the lobster claw piece on the center of the simple key case facing down.  Using an awl make two holes where the holes are in the lobster class piece.  Insert the studs that came with the lobster clips through the lobster clips and the fabric piece.  Place the backing on the stud.  Hammer with a stud setter.  

Add the lobster clips

Step 10: Add the Other Side of the Kam Snap

Fold the simple key case in thirds.  Find the location for the other half of the Kam Snap and Insert it at this point.  You have now finished your Simple Key Case.
