Begin the first row by chaining 30, making single crochet in the second chain right from the hook and until the end. Make sure to chain one and turn in the end.
Stitch two single crochets in the front loop of the initial chain you had made before starting up the second row. Carry on adding single crochet in the front loop, but have two single crochets in the last stitch before you chain one and turn.
As for the row three, you have to complete it by putting single crochet in the front loop, chain and then turn. You have to continue adding similar sort of crochets in the next four rows until you have completed seven rows.
The eighth row shall be made by crocheting only in the front loops, single crochets in each stitch across the row, chain and turn in the end.
Single crocheting in the front loop of each stitch is to be made in the ninth row and leave about 10 inches length of yarn before you fasten off.
Fold the short sides of crochet together and use the 10-inch length of yarn to sew them together with a needle. Keep stitching along the base chain and then join them at the bottom to complete the shape of the slipper. Fasten off the yarn at the ends.
