First, cut your fabric into a 15 inches x 2 1/4 inch strip. Then cut a piece of fusible adhesive the same size. Iron the interfacing onto the WRONG side of your fabric strip.
Then, fold your strip in half width-wise with RIGHT sides together. Then sew along the two long sides, using a 1/4 inch seam allowance. Don’t sew along either of the two short ends.
Turn this tube of fabric right-side out through the opening at the one end. Iron flat. Then zig-zag the open end closed. Then, fold the zig-zag end down 1 1/4 inches. Sew in place with two different seams….one using a 1/2 inch seam allowance and the other at 5/8 inch allowance.
Now, fold this sewn end over 2 1/2 inches onto itself and iron it in place. Then sew a double seam around all the edges of the holder, except for the folded end. The seam closest to the edge is 1/8 inch and the seam in from that is 1/4 inch.
Now, grab your 1 1/4 inch key fob hardware. And sandwich the hardware around the top end of the holder and center it along the top of the fabric. Then hammer the hardware flat, squeezing the fabric between the metal. Attach your key ring. And that’s it. So easy….. Enjoy!
