Crochet Sandals From a Simple Granny Triangle

Sharing is caring!

Add a unique crochet granny triangle to a basic pair of plastic sandals with this easy tutorial. Crochet around the straps in cotton yarn for an even more comfortable Summer sandal.

To create these crochet sandals, I snagged a cheapie pair of flip flops from HEB, one of my favorite Texas grocery stores. They only cost $2!

My niece mentioned that she needed new flip flops. She’s also learning to crochet so I knew she would appreciate a pair of crochet sandals.

Pattern Notes

  1. The granny triangle is worked in the round so you will join with a slip stitch and continue in the same direction.
  2. To start a round you will use a ch 3, which counts as the first double crochet stitch. I love using a ch 3 alternative for these.
