Welcome to the board. What a cute start to your quilt. Like the others have said if you want to make it bigger you should add more blocks to it. Since you used a lot of different colors and prints, you shouldn't have any trouble finding several solids or prints to go with it. I like to use lots of different fabrics when I make my quilts and sometimes they are coordinated in a fabric line and sometimes I just pick several different fabrics I like and put them together. The main thing is that you have fun making your quilt and remember, there are no quilt police.
