This is a pattern that it out there but I tweaked it a little so that it has more of a wide foot, mirror stitches and the sole is more shaped. Cotton is not stretchy and not all patterns work with this yarn. Use the 3-6 months size if the bootie comes out smaller than 3.25″ in the 0-3 month size.
Needle: #7 (4.5 mm) straight needles to seam up back or use DPNs to do in the round
Yarn: #4 – 100% Cotton Gauge: 4.15 sts/1″ or 16.5 sts/4″
Sizes: 0-3 Months 3.5″ foot, 3-6 months 4″ foot
Cast on 25 (29) sts starting at sole
Row 1: kfb, k10 (12), kfb twice, k10 (12), kfb, k1 (29, 33 sts)
Row 2-10: knit in garter stitch for 9 rows (29, 33 sts)
Row 13: k to 2 sts before marker, k2tog, sm, k5, sm, ssk, knit to end of row
Row 14-15: Repeat rows 12 and 13 one time (2 times) (19 sts)
Row 16-17: knit stockinette 2 rows and remove stitch markers (19 sts)
Row 18: kfb, *k1, p1*9 times for 1×1 rib fold over cuff (20 sts)
Row 19-35: *k1, p1* 17 (19) rows for 1×1 rib fold over cuff (20 sts)
Row 36: Bind off loosely with 16″ tail
Seam up back and mattress stitch the sole, weave in ends.
Variations: For a garter cuff , garter knit for 5 rows after row 17 and bind off loosely from wrong side or purl row for a 4 ridge cuff. 1) For roll cuff, stockinette stitch for 7-8 rows after decreases, then bind off loosely. For the 0-3 month size, you might want to do an extra decrease row because without a rib cuff it is a little loose so after completing last decrease, repeat row 12 to make a total of 17 sts.
