I had one of those wall mount thread holders. I couldn't see the colors of thread too well with mine because of the angle that the thread was stored on it. Also, all of my thread got dusty and dirty. I found I had to keep peeling off the outer layer before I could sew. So I got rid of it and went to the box method. I don't have trouble with tangles because I keep the thread ends in that slot on the spool. The bobbins were more messy until I got a box bobbin holder.
