Crocheted booties and slippers give warmth and comfort on chilly nights, but the styles are a little bit different. Booties have higher sides that warm the ankles in addition to the feet. Crocheting gives the booties a soft and spongy feel that adds to the booties' warmth. The yarn loops create air pockets that trap and hold warmth. Choose a soft and spongy yarn. Tightly spun yarns give the sole of the bootie a knotted feel, detracting from their comfort.
Wrap the end of the yarn around your fingertip. Push a loop through the circle of yarn. Tighten the circle to create a slip knot in the end of the yarn. Insert the crochet hook and tighten the slip loop to the size of the hook. Crochet a chain of 15 stitches. Turn the work and single crochet back along 14 stitches of the chain. Add one more stitch to the chain at the end. Repeat for 10 rows.
Single crochet the first stitch to the last to create a tube. From this point, crochet around the edge in rounds. Crochet one chain stitch then single crochet the rest of the row. Join the last stitch to the first. Insert the hook in the first stitch of the row, then crochet through the stitch. Repeat for five rows.
Chain one stitch and then single crochet. Decrease the size by crocheting two together, then single crochet. Repeat for the entire row. Tie off the end and close the toe of the bootie. Cut a two-foot length of yarn and thread a crewel needle, which is a large blunt needle. Insert the needle into one end of the open toe. Stitch through the top and bottom and tie the yarn off. Continue stitching across the toe, then tie off the yarn. Snip off any excess yarn. Sew the back of the slipper closed in the same way.
Tie the yarn to the top of the bootie. Single crochet in every stitch around the top of the slipper. Join the last stitch in the row to the first. Repeat for two more rows and tie off the yarn.
Use two strands of yarn together for a thicker and fluffier slipper.
Use acrylic yarn if you are allergic to wool or natural fibers.
