Materials List

  • 1 1/3 yd outer fabric (fleece or minky)
  • 1 ½ yd lining & tail fabric (fleece or minky)
  • Wrapping paper for pattern drafting
  • Sewing machine
  • Thread
  • Scissors
  • Chalk
  • Washi tape (helpful seam guide)
  • Straight pins
  • Free PDF pattern download


  1. Start by laying out a piece of wrapping paper or taped newspapers that are the same dimensions as your outer tail fabric would be if folded in half (this should be about 24 by 60 inches.)

  2. Then fold the paper in half lengthwise so it’s about 12 x 60 inches long. (Drawing our pattern on only one half will allow us to cut it out symmetrically.)

  3. I’ve included a printable pattern for the fin (click link above supply list). Print and cut out, taping together as shown. Then trace or tape this piece at the bottom of your wrapping paper, so you know how much fabric you have left to create the tail.

  4. Make the bottom of the tail the same width as the top of the fin. Draw a diagonal line from the bottom of the tail to the outer edge of the paper, then curve inward at top. Unfolded, my tail piece is 20 inches across at top and 45 inches long.

  5. Fold your outer tail fabric in half, right sides together (for my blanket, this is the green fabric). Pin the tail piece through both layers and cut out, creating two tail pieces. Do not cut a fin out of this material.

  6. Remove the pattern, then re-pin the two fabrics, right sides together.

Mermaids are all the rage right now for the little girl set. What a fun project to make with my daughter. Looks easy to accomplish.

Wow! What little girl would not like to cuddle up in this super soft mermaid tail while watching TV or lying in her room or even when going to bed. This is made with minky fabric so it is so soft and warm. So if you have ever wanted to make one for your little girl here it is. A super easy tutorial to make her one and why not make a couple more while you are at it so she can share one with her friend or make one for yourself and join in the fun.
