iPouch
This is a carrying pouch for your iPhone that you wear around your neck. Skills needed are Turkish cast-on, knitting in the round, and I-cord stitch. You will need to measure the width of your iPhone and calculate the number of stitches to cast on based on that measurement. The below cast-on is based on the iPhone XS
Materials:
Yarn – about 1.5 oz sport weight or 2.0 oz worsted weight yarn
(Used in example: Caron Simply Soft Paints 5 oz/141 g, 250 yds/228 m, colorway 21004 “Oceana”)
US-4 (3.5 mm) double pointed needles (or US-4 (3.5 mm) 24-inch circular needle if Magic Loop method used.)

Gauge: 18 stitches and 24 rows to 3 inches. Measure the width of your iPhone to calculate the number of stitches.
Pouch:
Using Turkish cast on, CO 20 wraps. (40 stitches)
Row 1: K
Row 2: kfb, k19, kfb, k19. (42 stitches) (42 stitches) (If your iPhone is thicker than 1/4-inch/1 mm, repeat this row.)
Row 3 and subsequent rows: k
Knit in round until work measures 1 inch longer than the length of the iPhone
Finishing pouch: K3, cast off 16, k5 and slip them off onto a stitch keeper, cast off 16. Do not break the yarn.
Cord:
Using a measuring tape, determine the length of i-cord necessary for the pouch to hang at the desired position on your chest. Be sure to take into account the width of the pouch in your measurement. Using the next 5 stitches, knit I-cord to that length.
When the i-cord is as long as you need it to be, take the remaining 5 stitches off the stitch keeper and put them on an empty needle. Put the needle with the icord stitches and the needle with the stitch keeper stitches side by side being careful not to twist any of the stitches. Transfer the 5 stitch keeper stitches and 5 i-cord stitches to another empty needle, by slipping one icord stitch, then one stitch keeper stitch, alternating back and forth until all 10 stitches have been transferred to one needle.
Bind off:
Attach the working end of the icord to the pouch in the following manner: k2tog, k2tog, ppso, k2tog, ppso, k2tog, ppso, k2toh, ppso. Break yarn and weave in ends.
