There is always gaps in the same place in my work, between row 1 and 2 (Amigurumi)
I always only get these gaps in row two. For example, 6SC in a MR, INC x6. Please check both photos to see my work doesn't have holes in other places. Does anyone know what this is about?
Edit: edit to add if you see anything else I can improve on my work please point it out
