Cell Phone Cover Made from Neck Ties?

2 easy methods:
1: Slip your phone into the middle at the widest end of the tie, and stitch up the sides to the correct length/height to form a pocket.
2. You will likely need to sew up that middle seam in the wide end front a bit, to close it up.
3. Flip the top over the this pocket, and cut off the excess tie. Sew up your seams
4. Either use velcro dots to close, or add a snap to close.
5. Sew a clip onto the top or a top edge so you can clip it onto your purse straps, a pant belt loop etc.
Embellish with whatever makes you smile.

Second version:
1. Fold the widest end of tie up as far as required to create the pocket for your specific phone.

2. Flip over the other end of the tie down until you have the correct amount of fabric to cover and close it properly.
3. Cut the tie at the right length, sew the seams to create your pocket, and lid cover
4. Add a snap or velcro to the ends as a quick method to keep it closed.
5. Embellish to your hearts content and you could add a length of cord -sewn tightly onto each top end, so you could wear this around your neck.

Sure hope this makes sense to you. Have the tie and cell phone in your hand and do the steps with them as you read along, it may help clarify.
Best of luck. You can do this!
