The biggest crochet hook I have is 6mm. So my gauge for the bottom is totally off.

I used the pattern for size 9 - 10 and crocheted two more rounds before the finishing round and adjusted the increases.

For the straps, I didn’t make any adjustment except using a 4.5mm crochet hook.

This is the most comfy slippers I have ever had!

I used leftover yarn from stash. I still got other colors to go with the grey: red, purple, blue…
