your small items in while at the pool including your credit card, cash, I.D, and whatever else you may need and don’t want to take your purse in.

I made this phone pouch from oil cloth and used felt on the inside to be extra soft on the phone.  I found my cute oil cloth material at Hobby Lobby and used some scraps of felt I had lying around (hence the miss-match):

You will need two pieces of oil cloth, and two pieces of felt.  I have an iPhone 5 and included the measurements below which are 5″x6.5″.  If you have a different phone, in the white text below I have shown you the measurements to do: Measure the width 2.5″ larger than your phone and 1.5″ length larger than your phone.

Once you have your pieces cut out, put one piece of oil cloth and one piece of felt together right sides touching.  Do this with all pieces and then sew along the tops of each pair.

After you have sewed a straight line on the tops, fold over so your fabric is right side out and stitch along the top as shown below:

Now you will place the pieces shown above together so that the rights sides of the oil cloth are touching.  Sew down the sides and on the bottom with a straight stitch.

Turn it right side out.

You could stop here if you want, but I wanted to sew a straight line along the sides and bottom again to give it a flatter look and to hold my phone tighter.  And then I wanted to add a flap, this was an after-thought.  I just measured along the top of my phone cover and matched the width to the flap shape below.  I folded the flap over and sewed along the sides:

I attached it to the back of the phone case with a straight stitch.  I then wanted a “belt-like” feature to hold the flap down.  I made this by cutting a long strip of oil cloth and folding over and sewing.  I wrapped it around the phone case and glued it on the back as shown below.
