Ribbed Stretchy Crocheted Slippers

A lifetime ago, my mom made me a pair of slippers which I really liked.  I haven't been able to find the pattern, so just did a copy-cat job with no pattern.  This is what happened:

 

My original plan had more black, but I didn't have any black that was the same weight as the grey and lavender, so it was relegated to trim. 

They are not exactly like Mom's - she used a different weight yarn, for one. I will make a few more changes next time! But for now they are a great addition to my music bag for when I am out and about. 

Maybe I will publish my own pattern when I am happy with the changes!  If anyone knows of a previously published pattern for these I would be grateful to see it!
