Socks for hubby! Cast on 38 on 2.0 Work short row toe keeping 38 each side Switch to 2.25 needle and work 23 rows increase 4 stitches (2each side) Work 50 more row and then increase again by 4 (2 each side) Now you have 42 per side Increase on sole only until you have 58 stitches then I lost the rest of instructions I am seeing something about having 76 plus 24 equals 100
