Divide for heel

Need some help on my first pair of socks.

I will have 8 stitches on each of 3 needles. How do I divide for the heel?

Transfer stitches around so that there are 12 stitches on the first needle, and 6 stitches on each of the other
two needles. Work back and forth across the first needle ONLY as follows:
Row1: Slip 1, knit to end.
Row 2: Slip 1, purl to end.
Repeat these 2 rows for 12 rows total, then work row 1 once more. The heel will be 13 rows long.

I think you will be working the heel on needle one. So, on needle 2, slip 4 stitches onto needle 1, making 12 for the heel. Then, on needle 3 slip 2 stitches back onto needle 2. I hope this isn’t confusing. You should now have 12 sts on one, 6 on needle 2, and 6 on needle 3. Hope this helps!
