Double your yarn by working with 2 strands. I rolled the yarn into two balls and worked from both.
SOLE Ch 4 Row 1 - 2 sc in 2nd chain from hook, 1 sc in next chain, 2 sc in last chain, ch 1 and turn. (5 sc) Row 2 - 1 sc in each sc, ch 1, turn. (5 sc) Row 3 - 1 sc in each sc, ch 1 and turn. (5 sc) Row 4 - 2 sc in first sc, 1 sc in next 3 sc, 2 sc in next sc, ch 1, turn. (7 sc) Rows 5 to 10 - 1 sc in each sc. (7 sc) Row 11 - 2 sc tog, 1 sc in next 3 sc, 2 sc tog, ch 1, turn. (5 sc) Rows 12 to 20 - 1 sc in each sc, ch 1, turn. (5 sc) Row 21 - 1 sc in each sc, ch 1, turn. (5 sc) Row 22 - 2 sc tog, 1 sc in next 1 sc, 2 sc tog, ch 1, turn. (3 sc) Next you will do a round of sc all around the sole in the following manner: Slip stitch in first sc, in next sc do a slip stitch and a ch 1 and 1 sc. 1 sc in next sc. 1 sc at the end of each row. You now have 24 sc, 1 sc in each of the 3 chs. You now have 27 sc. 1 sc at the end of each row. 1 sc in the 1st slip stitch you made at the beginning. 50 sc total, ch 1, turn.
BODY OF SLIPPER Always begin your sc in the sc of previous rnd and not in the ss where you joined. RND 1 - Through back loops of stitches only - 1 sc in each st, ss to join, ch 1, turn. (50 sc) RND 2 - Rest of the rnds are through both loops - 1 sc in each st, ss to join, ch 1, turn. (50 sc) RND 3 - 1 sc in next 19 sc, 2 sc tog, (1 sc in next sc, 2 sc tog) 3 times, 1 sc in next 20 sc (24 sm - 29 lg), ss to join, ch 1, turn. (46 sc) RND 4 - 1 sc in next 21 sc, 2 sc tog twice, 1 sc in next 21 sc, ss to join, ch 1, turn. (44 sc) RND 5 - 1 sc in next 20 sc, 2 sc tog twice, 1 sc in next 20 sc, ss to join, ch 1, turn. (42 sc) RND 6 - 1 sc in next 19 sc, 2 sc tog twice, 1 sc in next 19 sc, ss to join, ch 1, turn. (40 sc) RND 7 - 1 sc in next 16 sc, 2 sc tog four times, 1 sc in next 16 sc, ss to join, ch 1, turn. (36 sc) RND 8 - 1 sc in next 14 sc, 2 sc tog four times, 1 sc in next 14 sc, ss to join, ch 1, turn. (32 sc) RND 9 - 1 sc in next sc, 2 sc tog, 1 sc in next 9 sc, 2 sc tog four times, 1 sc in next 9 sc, 2 sc tog, 1 sc in next sc, ss to join, ch 1, turn. (26 sc) You may want to end the pattern here. But if you feel it needs one more row for height or to tighten up the slipper, do the next row as follows. RND 10 - 1 sc in next 9 sc, 2 sc tog four times, 1 sc in next 9 sc, ss to join, ch 1, turn. (22 sc) Fasten off.
