DIY Mermaid Skirt

Learn how to sew a DIY mermaid skirt with knit fabric. This is a simple two tiered skirt that is a beginner sewing project!

I’ve made my daughters lots of mermaid skirts and dresses. They wear them almost everyday until it has holes and stains. They just loving wearing dressups everyday.

When I make them they last longer than anything I can buy at the store because I don’t use cheap fabric, and I sew slower than a manufacturer which makes the stitches a little stronger.

This version of a DIY mermaid skirt is essentially two tiers with only one of them gathered so it is an easy version!

I had some leftover shiny scale fabric and let my daughters choose what color they wanted. Luckily, I had similar colored knit fabric for the tails.

When I did these skirts, I didn’t want to use that much fabric, but I wish I would’ve doubled the gathered amount to make the “tail” tier much fuller.
