Little Miss Mermaid

Ariel has been the princess of choice recently for our littlest (and honestly, there is no other choice.) It was also the first time requesting piggies which I really hope will continue.

Supplies needed:

  • base dress

  • Stiff felt in mermaid themed colors

  • Optional fabric with special patterning for the shell top

Creating a base for this from scratch was out of the question for me right now, but I am certainly not above repurposing! Found this mermaidy gem after a quick stop into my local ‘Once Upon a Child’. I was initially searching for something more aquatic, but the patterning on this one felt perfectly scaly to me. Let’s make it happen!

Using a semi-circle, the scale scaled to 2”x3” and cut out on stiff felt (using your personal mermaid color patterning preferences) on the Cricut, or by creating a template and cutting.

Shell exterior was cut on the Cricut, but can easily be freehand. Mark your shape by laying the cut outs on the felt and draw the shell shape with a slight trim around the outside edge.

For the Shell interior, I cut the fabric (or use specially patterned felt) on the Cricut, and put the shape over a pop of color in stiff felt to make them extra fancy fun. Place the interior shape onto the felt with fabric glue, or sewn. Sew shells in proper placement on the bodice. (My favorite feature.)

Tail fin and embellishments templates were created freehand on oversized stiff felt to have enough for both front and back (because you can never have too much tail fin.) Our Little Mermaid definitely appreciated the extra swishability this provided.
