Help with sewing up a baby blanket made of squares

Hi All
I am sewing up a baby blanket for my soon to arrive first Grandson - It is made up of separate squares and I need to match the pattern. The joins look scrappy and I don’t know what to do to make them look nice. Sirdar Pattern 3266 - a bit disappointed after knitting all 48 squares that it is not as lovely as I had hoped. Any ideas on how I might make it look better - happy to send post a photo if needed
