I need to make a baby quilt STAT! (Last minute invitation.) So I bought a charm pack of 5" squares, some cute baby prints, some solids. But I'm not sure about the size/proportions. Does it matter? If I make it 5 x 5 squares, I could do an X of solids. But is square weird? I want it to be small - any thoughts? I'm such a rank beginner, I truly don't know where to start!
