Big oops/oh, well

Last night I moved right along with my seaming on this blanket, but today I suddenly realized that I’ve been doing single crochet instead of slip stitch. This creates more bulk and uses more yarn. But I’m fine with the way it looks and I don’t fancy ripping out all the seams plus the woven-in ends!  

  
I feel silly though, especially after convincing myself that I totally remembered how to slip stitch and didn’t need to look it up. Lesson learned!!!
