You could always start with a monochromatic plan but if you get bored, maybe do an alternate color (even whites and creams mixed look rich together and the perfect contrast to any color).
I’m with you, though. I just can’t do the reach in and grab whatever to sew next. I like to start with a focal print of multicolors and choose prints in that colorway. Experiment but Stay true to yourself. We all have a gut reaction to color and styles that just feel natural and right to us. Unless you want a personality conflict with yourself, stick to what feels like “you.”
