Hi. The width is perfect for any mobile phone so you do not need to adjust any foundation chains, if you are making it as phone cover. You only need to add more rows with existing pattern. If you want to expand width, this pattern (Granny Stripe Stitch) works on multiple of 3. I hope this will work. Happy Crocheting. ❤️🧶❤️🧶❤️🧶
