For my Sock Class

As promised, pictures and directions from the Two Socks On Magic Loop class today.

Gusset pictures:

Here, I've knit across the remaining heel flap stitches and picked up stitches along one side of my gusset. I'm about to knit across the stitches in the top of the sock.













This is the bottom of the sock after picking up the stitches on the second side of the gusset.












This is the working view of the sock after picking up the second side of the gusset. The heel needle has far more stitches than the needle holding the stitches for the top of the sock.





Heel Options for Toe-Uppers (and some that would work for top down, as well)

My personal favourite, the short row heel, works with both toe-up and top down socks. Working on your heel stitches only....
Row 1: Knit to last stitch. Move yarn to the front, slip the last stitch, move yarn to the back and slip the stitch back to your left needle. You've wrapped your working yarn around this stitch. Do Not Knit this stitch.
Row 2: Purl to last stitch. Repeat the slipping and wrapping.
Row 3: Knit to last unwrapped stitch. Repeat the slipping and wrapping.
Row 4: Purl to the last unwrapped stitch. Repeat the slipping and wrapping.
Repeat rows 3 and 4 until you have 2/3 of your heel stitches wrapped (1/3 on each side), end with a purl row.
Row 1: Knit across the unwrapped stitches. Pick up the wrap that is around the next stitch and place it on your left needle. Knit these two stitches (the original stitch + the wrap) together. On the next stitch, repeat the slipping and wrapping from above. This stitch should have 2 wraps.
Row 2: Purl across the unwrapped stitches. Repeat as above.
Row 3: Knit across the unwrapped stitches. Pick up BOTH wraps from the next stitch and place them on your left needle. Knit all 3 stitches together.
Row 4: Purl across the unwrapped stitches. Continue as for Row 3.
Repeat Rows 3 and 4 until all stitches are worked. You will not need to work a gusset, simply continue into the leg (or foot) of your sock.

Another option is the toe-up heel flap:

Row 1: S1, K1 in the purl bump, k to last 1 stitch, k1 in purl bump, k1
Row 2: S1, purl across
Row 3: S1, knit across
Row 4: S1, purl across
Row 5: S1, k2, ssk, knit to last 5 stitches, k2tog, k3
Repeat rows 4 and 5 until 14 stitches remain
Next row: S1, purl across
Work shortrows
Row 1: S1, k2, k2tog, k4, ssk, TURN
Row 2: S1, p4, p2tog, turn
Row 3: S1, k4, ssk, turn
Row 4: S1, p4, p2tog, turn
Row 5: S1, k4 ssk, turn
Row 6: S1, p4, p2tog, turn
Row 7: s1, k4, ssk DO NOT TURN. With right side of heel flap facing you, k1 through the slipped stitch immediately below the stitch you just knit, TURN.
Row 8: S1, purl across, p1 in slipped stitch below the last p2tog.
Row 9: S1, knit across, k1 in next slipped stitch
Row 10: S1, purl across, p1 in next slipped stitch
Repeat rows 9&10 until all slipped stitches are worked
Next row: Pick up and knit one stitch in the ladder between the heel flap and the body of the sock. Knit across the top of the sock. Pick up and knit one stitch in the ladder between the body of the sock and the heel flap. Knit across the heel stitches.

You could also use a peasant heel for either toe up or top down socks.
