PLEASE HELP...I have started a baby blanket twice now and have had to tear it apart both times. I am very new at all of this. I seem to be getting the stiches down fine. The problem I have is after I start the blanket it seems to decrease in size. Almost shrink I guess you could say. Is there something that I can do to prevent this. It looks so nice half way through until I realize how uneven it is. So frustrated. Any help would be much appreciated. thank you.
