Lost pattern

I’ve made this blanket many times but cannot find the link nor a printed pattern
It starts 20 sts 40 garters st rows, cast off leaving last st on needle. Pick up 19 more sts down left hand side, knit 40 rows, cast off leaving last st on needle. pick up 19 more sts down left hand side and knit 40 rows, cast off leaving last st on needle. The next square is mitred and the original pattern had photos showing which way to turn and pick up the sts. It’s not totally mitred, I’ve looked through 50 pages of Ravelry blanket patterns and looked at other sites but no luck

Welcome to KH!
I couldn’t find a combination patchwork and mitred square blanket. It sounds intriguing.
The closest I came was the initial directions for a log cabin blanket which has a video. Not quite the same but maybe your good instructions, a diagram .and the video would help put the pattern together.

Ive found it hidden in my Dropbox files

Don’t know if you’ve seen my reply but this is it


I’ve made it square but I’ve also adapted it to make an oblong single bed size

Oh, terrific! Thanks so much for posting the pattern link.
