Here is a step by step tutorial for making a swimmable mermaid tail. Check out Video #2 for a demonstration of the tail in use!
Q: Where did you get your monofin and how much did it cost?
A: I got my Finis Tempo monofin online for about $50. Try ebay or searching on google.
Q: How did you make your top?
A: I covered an old swimtop with material.
Q: How do you get the monofin in and out?
A: You can either leave the bottom open and extend your fabric a few inches past the monofin, or just roll up the monofin and work it in and out.
Q: What is the material called and where do you get it?
A: It is just swimwear/dance material. You can find it at craft stores that carry a variety of fabrics. It comes in all kinds of colors and designs. Mine happens to be a teal hologram material. Jo~Ann fabrics is where I go.
Q: How much is the material?
A: Depends on which material you want. At JoAnns it is $15 a yard and 2 yards will make a tail.
DISCLAIMER: Always use proper supervision when swimming with your tail. Swimming with the legs bound together is very dangerous and should only be attempted by trained persons.
