Crochet Sandals From a Simple Granny Triangle
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.

Basic Granny Triangle Pattern:
- Start with a magic circle, or Ch 3
- Slip stitch to first chain. You will crochet into the circle formed here.
- Rnd 1. Ch 3, place 2 DC into the circle formed from first step, then ch 1
Continue and place 3 DC into the circle, then ch 1- Place 3 DC into the circle, ch 1 and join to 3rd chain of the beginning Ch 3. Round 1 is complete.
- Rnd 2. Slip stitch over to the next ch 1 space and place (ch 3, 2 DC, ch 1, 3 DC) all into that space. This forms the first corner of the triangle.
- Skip to next chain 1 space and place (Ch 3, 2 DC, ch 1, 3 DC) this is the second corner.
- Skip to last chain 1 space and place (Ch 3, 2 DC, ch 1, 3 DC, ch 1), join to 3rd chain of 1st stitch. This forms the 3 corners of your triangle. Round 2 is complete.
- On the next round, slip stitch over to the next chain space.
- Rnd 3. Ch 3, 2 DC, ch 1, 3 DC, ch 1 all in the same chain 1 space, skip to next chain 1 sp and place (3 DC, ch 1) all in this chain 1 space.
- Continue to the next chain 1 space and place (3 dc, ch 1, 3 dc, ch 1) all in the chain 1 space, this is a corner.
- Continue to the next chain 1 space and place (3 dc, ch 1) all in the chain 1 space, this is a side.
- Repeat the last two steps one more time.
- To finish your granny triangle slip stitch to the top of the 3rd chain from the beginning of the round. This completes Rnd 3.
- My sandals were crocheted for my niece so they were womens’ size 5-6. So this granny triangle was perfect for these crochet sandals. For larger sizes you might need another round, just follow the pattern of (3 DC, ch 1, 3 DC, ch 1) for the corners and 3 DC, ch 1 on the side chain spaces.
