Watermelon Swimsuit Cover

Bathing Suit Cover-up Watermelon

I had originally designed a Watermelon shirt, but once I got started on the project, I decided it would be so much fun as a beach cover up.

So, I made a few small tweaks and I’m loving the finished piece!

It’s pretty late in the Summer season, so I’ve decided to forego sizing this pattern and instead I’m just going to give you a tutorial of how I made this one. It’s intended for a size 4 (4 year old), but it will easily fit on a 2 year old (it will just be longer), plus it is stretchy enough to fit over a slim or average 6 year old.

Let’s get started!

Skill Level




  • Beginning chains do not count as stitches
  • After round 2 the cover is separated into four sections: 2 shoulder strap (short sides) and the front panel/back panel (long sides).
  • The back panel is longer than the front panel.
  • 8mm hook is used for the main portion; 10mm hook is used for the edging.
  • To size for larger covers, you will need to add at least 4 to your beginning chain, to make the panels wider and shoulder straps longer.

Special Stitches

Decrease (dec) = insert hook in 1st stitch, draw up a loop, insert hook in next stitch, draw up a loop, yarn over, draw through all loops on hook.
