Aquarienne Beach Cover Up


  • Breezy customizable, convertible, versatile layer.
  • Crochet it side-to-side in Tunisian crochet filet lace.
  • Two triangles with a self-edged beaded fringe are laced together different ways to seam.
  • Only one 256-yard ball of our Lotus or other sport weight yarn (plus scrap amounts of two contrast colors).

More details below.


Aquarienne is a convertible layer of two identical triangles of filet Tunisian crochet. Each is crocheted point to point (a.k.a. side to side in this case). They’re edged as you go with sparkly “water droplets” (a beaded twisted fringe) because that’s how I roll.

No pre-stringing of beads required. Remarkably, only one 100g. (256-yard) ball of the main color yarn was needed, plus scrap amounts of two contrast colors. Filet-style Tunisian crochet is not a yarn gobbler.

Lace together the colorful linen stitch band several ways: partially unlaced for a poncho, one-sleeved vest, or full-sized V-shawl. Wear the lacing in the front and back for a V-neck, or at the shoulders for a bateau neckline.

My goal was to design a breezy, versatile beach cover up that would be fun to wear here in Florida at the peak of summer (i.e. June to October).

Skill Level

Advanced Intermediate. Two simple Tunisian stitches make a one-row filet-style pattern. Its loose gauge and laciness add challenge; so does starting it in one corner and steadily increasing at one end of each row with a built-in beaded twisted-loop fringe edge. Don’t worry though! Pattern has professional stitch diagrams, a schematic, and video tutorial.

Stepping-stone patterns to build up to an Aquarienne experience would be Diamond Ennis. Also, Aero or Minuet.

After using this pattern, you will know (if you didn’t already):

  • How to crochet a strikingly open net of Tunisian crochet stitches.
  • How to crochet a triangle by starting at one point and ending at the opposite one.
  • How to add a finished edge with beaded twisted loops as you complete each row.
  • How to combine two lacy triangles to create a convertible garment.
  • How to apply principles of filet crochet to Tunisian stitches.
  • How to add beads without pre-stringing them.
