Mermaid Tails For Kids

-Fabric, at least five yards. Make sure that you choose a fabric with stretch in order to keep it comfortable and flexible for movement. I recommend using cotton lycra or knit jersey (or any other similarly light weight fabrics) because they are available in many different colors.


-Measuring tape

-Thread and sewing machine on heavy duty needle

-Scissors of some kind (preferably dressmaker’s shears)

-Six large safety pins or binder clips/clamps to hold pieces together while stitching them up, to make things easier. If these aren’t available, two people can work as clamps by holding the edges of the fabric together so seams don’t tear apart .

-Sewing needle (sharp)

-Zipper foot for sewing machine if you have one. If not, a regular foot will do just fine. It’s your preference which type of foot to use as long as it makes the job easier and/or faster. I’ve listed these items in order from what is most important to obtain first through those that are optional:
