Hi. I'm making a baby blanket for my friends imminent baby. I've knitted all the squares on the diagonal.
I have 4 8inch squares for the corners, and the rest are 4inch squares in different colours. I know the pattern I want to sew them up as, but think I might have scuppered myself making different sizes. 
Any tips please? Should I sew all the little ones first, then the corners? Or sew in lines?
TIA.
