I have very little floor or drawer space so I went to the walls using pegboards. I use only one brand of embroidery thread too so got their thread chart and organized them to follow the chart. I even went to the trouble to label each hook so when I go to put the spools back I know where they belong. Obviously I have too much time on my hands. Just added another large pegboard for my quilting thread but since I don't have a thread chart to follow I just organized them in color families from dark to light. Have 2 brands of quilting thread so I keep them separate. Plus I purchased metallic embroidery thread for quilting only so have placed them at the bottom of the board.
